Finding Errors

I've spent the past couple days scanning my code, trying to find where things are going wrong. No luck. So, I've sent a desperate email to my sister asking for help, and in the mean time, I'm starting to comment everything. Hopefully, in writing the comments for all my code I'll be able to find out which parts don't work because I'll have to find out what each part does. It's super tedious, though, even worse  than layout. That's probably why I've put it off for so long - ideally I should comment as I go along, but I'm just too lazy, and I guess that's how I end up in these situations. Oops...
