Stepping through a script line by line

[Chakusin]

Hello everyone,,
Is there a debugger or another way to step through a script that I'm updating?

I notice that several scripts are not working.  Nothing is being displayed when I know the tors are out there.  The two that I checked were torrent-damage and elbitz.   I took a look at the scripts and saw what I believe is the problem.

Select only the script you want to debug & press F12
