Description of the problem:
Project name: HABIPOS; Project ID: 88796
Hi, I’ll be forever grateful if you could help me 
The project runs well on my computer (mac) but doesn’t work at all on pavlovia.
in the project I added a code quit similar to the one entered here:
At first, it said “the experiment is initializing”, but it never went past the loading stage.
I downloaded the new version of Psychopy in the hope it will work things out, but it still doesn’t work now I get this massage:
Traceback (most recent call last):

TypeError: str returned non-string (type NoneType)
During handling of the above exception, another exception occurred:

TypeError: Value of parameter image of component iname_block1 could not be converted to JS. Value is $imagesb[$number1]
**I tried to set $imagesb[$number1] differently (e.g. without using a variable, such as $imagesb[1]), but it still doesn’t work.
Thanks in advance
