Forgive the stupidity of the question, but I am an experienced Excel user
trying VBA for user forms for the first time.

I have an Excel spreadsheet that is a 2 column Cost Savings Calculator. It
compares costs between two different products. The formula is fairly complex,
so I created a VBA user form.

My problem is that it looks great, but I can't figure out the coding. I
basically need the Excel cells to populate the corresponding VBA form fields.
