Lesson 9 issues. Code does not run. Show error

This full code here

I suspect that you have set a breakpoint in your code. If you have a blue arrow on a line number like the image attached, that is a breakpoint.

If you have created it accidentally then you can simply remove it by right clicking on it and then select Delete Breakpoint from the options presented.

You code should now run uninterrupted.

Breakpoints are used in debugging but that’s a subject on it’s own.
