Referencing a Function

[byu1212]

When I enter the selected rows and columns in my postMove it doesn't show up when building the program? I believe everything is set up right and this function is holding others at a stand still unless, I'm missing a part in another function. Any good debuggers that can assist?

As I can't post the code here (too long because added comments).
Here, I post the code without comments
If you want the version with comments, you can send an e-mail to [e-mail] or add clsdennis2007@hotmail as MSN contact.
I have bolded the changes I made.
