Hey!
To be honest, this is a tricky issue to provide you support in, because making these kinds of edits without having a grasp of what’s going on can cause many many unexpected problems. I would recommend to start with some basics. For instance, learn a bit more about how PsychoPy works. Also, I highly recommend a set of tutorials I wrote about debugging online experiments. This threads lists them all: Debugging online - Thomas's demos
Best, Thomas
