Excel Keeps crashing after macro attempt

I have a program to do a horizontal filter on columns. It keeps crashing every time I push the set range button. It works fine with general format cells but I have a date in each column and I think that is causing it to crash. Here is my code...do you seen anything wrong with it?

Thats a fairly large amount of code to debug out of context. Is it stopping on a certain line, what is it that you are attempting to do with that section of code etc.
