I have a worksheet ("MySheet") with about 300 lines of code in the
Worksheet_Change event. When a user opens the workbook, MySheet will be
copied as many times as the user indicates (maybe up to 30-40 times). As a
result, my 300 lines of code goes up to about 12,000 lines.

I am wondering if it is possible to put the code into a separate module, and
then use the Worksheet_Change event to call the code from that other module.
