Hello!
I’ve designed a simple experiment for children using the builder part of PsychoPy3. It includes a feedback as well and it runs perfectly offline, but online I get an error message.
The feedback itself is supposed to be very simple. After giving a correct response, children are supposed to see a new image appearing. If they give a wrong answer, they should see the image that appeared after their last correct answer. The code was written this way:
In the picturefile part all the pictures are listed.
I get this error message, where image_2 is a component which is defined as $picture from the code part above.
Does anyone have any tips about how to solve this issue? I am not very familiar with coding, so any idea is well appreciated
