Problem to synch to pavlovia

Online experiments

Hello,
I have been working on my study today and figuring out how to counterbalance the three tasks in my study. Once I finally figured it out this PsychoPy3 Error showed up every time I try to synch my study to Pavlovia:

Traceback (most recent call last):
File “C:\Program Files\PsychoPy3\lib\site-packages\psychopy\experiment_experiment.py”, line 808, in findPathsInFile
filePath = eval(filePath)
File “”, line 1, in
NameError: name ‘expInfo’ is not defined

During handling of the above exception, another exception occurred:

SyntaxError: invalid syntax

I wrote my own code to try and counter balance the 3 tasks in the study and I am not sure if the issue is that as this error message only began after I added my code in but this is the code I wrote:
if ((expInfo’participant’] % 2)){
group = “1”;
} else:{
randNum = Math.floor(Math.random() *2)
if (randNum == 0){
group = ‘2’
} else {
group = ‘3’
}
}

It seems to work when I run it on Psychopy so I thought I wrote it correctly but now I am not so certain. (I’m extremely new to coding and don’t know much at all)
Thank you so much,
Victoria

Your code seems to have a Python: as well as a JavaScript {

In my crib sheet I recommend writing Python code in auto translate code components whenever possible.

Thank you so much, I thought that was probably the issue. woud you mind highlighting the bits which are in Java. I am very new to all this and I have no coding knowledge whatsoever! I have just been googling what I am trying to write but its not going very well :sweat_smile:
I’ve looked up two instruction videos on how to write the code I wanted to write and half of the code uses a video that I think used java and the other was one that was python!

If you type Python code into an auto translate code component then you’ll get an error on the JavaScript side if your Python code contains major errors.
