you have to get the errors to find out what is going on
Lol at the amount of errors here. Like half the code was missing. The other half does some very weird stuff. Anyhow this is the error free version.

I apologise, i thought you copy pasted this code from somebody. Didn't realize you were learning to code and coding your EA.
When I tested your code in my editor, it seemed like half of it were missing in places - unended if statements, for loops, functions that should be in loops (deduced by context) and weren't. That's why I also commented that something (as in some blocks of code) seemed missing.
Try it out, see if it works the way you planned it! :)
