I'm aware of a similar thread posted years ago.

I've followed the procedures from that post. However, I when running the experiment, I've encountered a series of "Error" messages.
The first Error states "Line: 70, Char:2531, Error: Expected identifier, Code: 0" and the second Error states "Line: 0, Char: 0, Error: Script error", Code: 0.

I believe these issues have something to do with my code but am unable to pinpoint the issue. May I know where did I go wrong?

Thank you!

Edit: below is the code I used for my html file.
