I'm not sure of it's purpose but I'll tell you what I'd like to do with it.
I'd like to open a workbook and have one of these pop up as a form that I
create. I'd like the data entered into this form to collect in the rows and
columns of a related 'Sheet', sequentially.

I have no idea how to program Excel. Is it possible to do this? Is there a
popular third party application designed to do this. I need help - has
anyone done this before?

Thank you for the help. This is something I've been curious about for some
time.
