Hi, I’ve been stuck with this problem for quite a few days now. So, every time I tried to give feedback in trial (whatever the experiments are), my responses were detected as “incorrect”, so the feedback just said that it’s wrong. I just curious why this function did not work properly on my experiment. So, I create a simple task about math, and still I never got the “correct” feedback. Because I can upload the file here, I’ll just post what I do in the builder.

In the begin experiment, I have this line:

```
msg=''

```

And in the begin routine, I have this line:

```
if key_resp_2.corr:
    msg='correct'
else:
    msg='wrong'

```

And the result in the ms. excel, the “corrAns” values and the “key\_resp\_2.keys" values are the same, but still the “key\_resp\_2.corr” values were all 0. Please anyone help me.

I also already put the code component above the text component in the feedback routine. And already set it to “every repeat”.

I’m using the latest version of psychopy, 64 bit.  
Any idea for this problem?

Thanks in advance!

In the keyboard component have you put the correct answer as `$corrAns` or or just `corrAns`?

The latter means that the correct answer is the actual key called corrAns!

I’ve post my “.psyexp” file in the old mailing list, since I can’t upload it here. Last time, Michael told me that it works fine for him, but it didn’t work for me. I don’t know whether it is a kind of bugs or not. And I’ve also tried the stroopextended experiment, and again, the feedback always show that my responses were “incorrect”.

This is what I’ve done. I also have the “corrAns” column in the ms. excel and no misspelled.

Really hope I can solve this issue.  
Thank you for the response!

Puzzling. I think we can rule out any problem with your code component. The fact that `key_resp_2.corr` is listed as 0 in every row suggests that code isn’t the problem.

Would you mind compiling the experiment to a script and sending that here? We don’t normally ask for that (it isn’t normally the easy way to find errors) but, if the experiment was working correctly on @m-macaskill’s machine and not yours, I wonder if the script is being compiled incorrectly on your computer.

This is what I have in the coder. I’m a newbie in phyton, so I don’t understand if maybe there’s something wrong. Thank you Jon!

Well the script looks fine. Maybe you could add the following code into the code component where you have your feedback checking:

```python
print("keys: %r" %(key_resp_2.keys))
print("corrAns: %r" %(corrAns))
print(corrAns == key_resp_2.keys)

```

NB The %r symbol tells python print not just how the string of how the object looks (because `"1"` can look the same as `1`) but its _representation_ as a string or unicode or integer etc.

Thanks

Dan, the key in the data file reports `9` not `num_9` so that doesn’t seem to be the issue. Is very weird 😕

Jon, you are right you cannot sneak num\_9 past, however, you can sneak 1.0 by because excel/libreoffice displays 1.0 as 1. It is quite possible that the issue is in the conditions file. My conditions file is:

```
corrAns
1.0
```

Good point. That should be picked up by print("%r" %corrAns)  
I think we need to hear back from @Lily_Kusuma to know more

Hi Jon & Daniel,

Sorry for the late reply. I just got back home today and checked here. I’m not sure where I should paste the code, so I just attach the pic here. Should I did it like this (paste it in the begin routine) or should I paste it in another place? I tried to run the experiment by adding the code like the pic below, but still, it won’t work. So I guessed I paste the code in the wrong place.

 ![](https://us1.discourse-cdn.com/flex002/uploads/psychopy/original/1X/ce7460d47eadc8ef4464ba494d9b427dc9ad29ba.png)

As I mentioned before, although I change the “corrAns” to alphabet, for example ‘a’,‘b’,‘c’ etc, it still did not work, and the stroop extended experiment also did not work on my laptop here (although that experiment were using ‘left’,‘right’,‘down’). I’ve been guessing that maybe the problem is in the conditions file, but couldn’t find what it is.

Thanks for the responses! Really appreciate it.

Update:  
I also had this message:

(Not sure what it means).

The idea was that this would output some information for us to work out what’s wrong. What was printed when you ran it this time?

Just the same as before @jon. My responses always detected as “wrong”. Should I just put the code in the begin experiment like the one I did in the picture above? Not sure if that’s the right way to do it.

No, we need to know what was **printed**. In the output window when the experiment finished there should have been more info from those print statements

Ah, sorry I didn’t understand. This was the output that I got after the experiment ended.

That doesn’t seem to include any print statement outputs. Are you sure this is the version with that new code added? Did you run from Builder or did you accidentally go to Coder instead?

Sorry Jon, I guessed I did it wrongly before. I tried to run it again from the builder. This is what I got. What I don’t understand here is, why the corrAns has “L” letter.

Another update:  
I also tried to run another experiment. And here’s the print statement outputs. As we can see here, some of my responses, although detected as correct below, but when i ran the experiment, it just told me that my responses were all “wrong”.

This one was different from the experiment I shared before (simple math experiment). This time, the outputs did the job well, it correctly told me whether my responses were correct/wrong, but still when I ran the experiment, it just said my responses were all wrong. I was pretty confused right now. And I also don’t know why there were “u” letter in my corrAns.

Thank you!

@daniel.e.shub 's suspicion seems to be correct, that the correct answer column in your conditions file for some reason is being interpreted as a number rather than as text. i.e. the character ‘8’ (with quotes) is not equal to the number 8 (without quotes). The L here indicates what sort of number it is (a long integer, I think).

If you are using a .xlsx conditions file, try switching to .csv, or vice versa. Excel files are more likely to have formats specified for their cells which get carried over in the import process, but on the other hand, the .csv importer we sue also sometimes does unexpected things. Try switching, anyway.

In the second example (you don’t really explain why the conditions have changed to use letters instead of numbers), the comparison is working correctly, as both the keys and the correct answer are strings (i.e. characters). Ignore the ‘u’ prefix, that just says that that particular string is encoded as Unicode. `'a'` still equals `u'a'`.

So PsychoPy is getting the comparison correct in the keyboard component in that case. I your code says that the responses are wrong, presumably there is an error in that code.
