Hello,

Glad to hear that you got it working.

Simply enabling the Developer Tools shouldn't affect the processing of your code, so I think something must have changed. I take it when you run the code without F12, it is still working? Correct?

In terms of getting started with debugging, and breakpoints, I would suggest that you take a look here:
