Problem with implementing the Canvas

VisualSearch_JavaS.osexp

I followed the intermediate tutorial for Visual Search exercise and built the programme as attached. At first, I could run it without any problem. However, this week, it kept showing error message on c.show(). May I have some advise on how to fix the programme. Thanks a lot.

Hi @abeque ,

The issue was that you put quotes around the run-if expressions in the trial_sequence. It should be correct == 1 and not 'correct == 1'. Why this results in an error message that points to somewhere else is unclear to me (and I would look into that), but this is definitely the cause of your issue!

PS. In the future, please include the actual error message and other relevant details when you report a problem!
