Dear all,

I have read through a lot of “stuck on initialising experiment” threads, but I still cannot seem to fix why I am stuck on this page. The experiment works perfectly without running online. I have looked through the crib-sheet for mistakes.

There are no longer any imports and I do not see any indication of what the problem could be.

I am very much hoping that somebody could shed insight into this as I am completely stuck. If any other information is needed, please let me know.

Best regards,

Snoek

Thank you for your reply.

The file does exist, though the .py version is not in my html folder. I can drag it to my html folder.

Only the two js versions need to be there. I’m not sure of the issue but I was wondering if it was due to file renaming.

I have made a new experiment to see if it has something to do with this, but the same problem occurs.

What code components do you have in Begin Experiment blocks? I find it easier to read Python code with notes for any manual translations.

Its possibly due to the use of the percentage symbol in your file name.

I seem to have gotten it to work now. It is, however, now stuck on the first screen. I am supposed to be able to go through the instructions with my arrow keys but I cannot move past the first screen.

As it seems related I found this earlier post: [https://github.com/psychopy/psychojs/pull/7](https://github.com/psychopy/psychojs/pull/7)

It recommends that JS type keys should be added: ‘right’, ‘left’, ‘ArrowLeft’, ‘ArrowRight’

I just saw that Internet Explorer may not work well in an earlier post, so I opened the experiment in Chrome and I am getting this error:  
**Unspecified JavaScript error**

I edited my code somewhat if that helps, and the JS part is not in this part of my code. I did add the shuffle, the win and thisExp codes to JS.
