Unable to export HTML

Hi, I tried File - Export HTML for the same Builder experiment in both Mac and Windows but got the following error. The funny thing is that this experiment was downloaded from one that’s on Pavlovia already (with an accompanying .psyexp file) yet could not be exported again to the online version (html, js…).

Any help would be much appreciated.

That’s a strange one… It looks like the only path in your file is being interpreted as a float rather than a string, could you share the .psyexp? I’ll try and track down what is being misread so we can account for this in future

You can find the link to the folder (with the builder file in it) hyperlinked to “one” in my original post. Here’s for quick reference: https://gitlab.pavlovia.org/tonytbui/Gamble_task.git

Hi @TParsons,

I am having similar issues although the error it throws is slightly different. It still compiled fine this morning and now that I finished a new experiment it refuses to compile:

A slightly earlier version of the experiment using 2020.1 (which the new one is based on but I changed to the newest version) still works fine to compile though. Any help would be much appreciated.

Just to add what the problem may be (at least in my case), when copying whole routines from an experiment that was created using 2020.1 to an experiment that is supposed to run as 2020.2 it fails to compile.
Copying single components seems to be affected as well, although I feel like this is not true for code components.

Also when I attempting to copy things between experiments, I get the following error in a separate pop-up window

Traceback (most recent call last):
  File “/Applications/PsychoPy.app/Contents/Resources/lib/python3.6/wx/lib/agw/aui/auibook.py”, line 2427, in OnMotion

I think these are both the same problem - there is some value somewhere in your experiment which is not convertible to a string, causing an error both when compiling to JS and when copying between experiments. @tonytbui, when I follow the link it says file not found, have you recently moved or renamed your experiment? @Julia_Landsiedel if you could also post your .psyexp file it would be helpful too as I could look for illegal characters, instances from external packages, etc. and try to track down what the str function doesn’t like :slight_smile:

@Julia_Landsiedel it looks like, in your mainText you had set the text to be

#$TaskInstructions;
$tempInstructions; 

as a way to comment out the other instruction text. Actually, $ doesn’t really mean “this is a variable” it means “treat this box as code”. PsychoPy does it’s best to interpret that correctly but this time it was confused when trying to move that to JavaScript! :wink:

If you change your entry to maintext to be this:

$#TaskInstructions
tempInstructions

does that fix the problem?

We’ll try to work out how to tell PsychoPy to interpret your code the way you intended but it might be tricky! :slight_smile:

Thanks for spotting this Jon and for clarifying my slight mis-conception of the $ symbol. I think I started using it with variable names as I had an error/problems with just using the variable name (although I might mis-remember this).

Your corrected code bit makes perfect sense and indeed solved the issue. :slight_smile:

Hi all, I am having a similar error, maybe this will shed light on the situation. In my case, the final message relates to one of the .csv files that I added for a loop. Something in the text is not being interpreted correctly (weird since this is the last cell of the .csv file and not the first, and they are all formatted similarly)

Perhaps it is trying to interpret the cell as code?

EDIT: this last cell in the .csv file had a $ sign within its text. Removing this got rid of that particular error.

Do you mind indicate where to change this? I am running into the similar issue with MacIntel 2020.2.5 veriosn. The experiment was downloaded from pavlovia github and changed using the same system.

Thanks!

Sorry to bother again. I found out the issue happened with my condition file. The conditions contain $ at the begin.

Do you mind point to me a way to still have the condition “$ _” as varible to show in the loop?

Thanks!

Why do you have $ signs in your cells?

If you have file names like $29.xlsx then I suggest that you change them to, for example, c29.xlsx.

The text stimuli is about how much dollar. Thank you.
