Need help with ReferenceError

I am able to load the participant box in pavlovia but right after that, a reference error appears. What can I do?

looks like you are presenting something is ocuring on line 89 of your experiment.

Click on the error message in your console corresponding to XPSUPRA1.js:89 - that should take you to line 89 and tell you where in your experiment you have an issue.

Best practice for fixing your issue is outlined here Syncing with a Builder experiment from Coder View

hope this helps,
