I’m trying to diagnose how to change the marker size in Pavlovia, TypeError when running on Pavlovia → Runs fine on PsychoPy - Online experiments - PsychoPy
I’m curious about your JS code in Begin Experiment setting
markerSize = 35;
It looks like you’re using height in the slider size (based on the decimals), but your marker size is 35. If your marker is just the standard circle, your marker might be there but enormous and off the screen.
