This means there is a JS syntax error somewhere.
- open developer tools as described in crib sheet.
https://discourse.psychopy.org/t/stuck-at-initialising-the-experiment/16406/2?u=becca - click the red error message that has the name of your file (with the .js extension).
- that will show you the line of code where you are having the error - go back to your BUILDER to fix it (e.g. it looks like an error in a text component, go to that text component to try a new option, refer to JS crib sheet for help)
Unexpected token ‘,’ means you have a comma somewhere that you need to remove, if you click on the error message in the console it should tell you what line that comma is on.
