Excel Crashes when trying to save after running a sort macro

I have attached the workbook. there are 5 sheets. all the sheets have text boxes that when clicked run a macro. the textbox labeled Sort runs the CustomSort macro. when i run the sort macro in sheet 2 named Blank with part (2 Columns) it saves fine.

But if i run that same macro on sheet 4 named Blank With Part (4 Columns) it will run the sort macro but after that i try to save it and it crashes. it does not crash when i run any of the other macros so i have narrowed it down to the customsort macro.

I just dont understand why it would work on one sheet and then not the other.

this is driving me crazyyyy

any help would be awesome

i have already tried clearing my temp files and that did not help


thanks
