I had the following goal. The end user will enter numbers into one
spreadsheet. But when they close it, I want to take number they typed
in and put it into another spreadsheet.

The trick is that I do not want to show the recieving spreadsheet on
the screen. Basically, the spreadsheet that is going to be updated
needs to be hidden from the end user.

I believe that I did this once but for the life of me I can't remember
how.

Regards
