Trouble exporting userforms

Hi,

I have attached my workbook for reference.

Problem: When I run my macro in module1 on my computer, it works perfectly. When I transfer the excel to another computer and attempt to run it, for some reason my userforms don't get exported to the temp. string like they should, hence my code won't run. The macro can be run from the command button at the bottom of sheet1. Any suggestions?

Thanks
