How can I add something to a variable each time I run the macro? So
basically, I have a variable called CountRows, and each time I run the macro,
I want CountRows to increase by a certain number (different each time it is
ran). I just want it to keep a tally. So I have another variable called Rows.
I thought I could do the following:

CountRows = CountRows + Rows

Then the next time it is ran for a different sheet, it will remember what
was in CountRows and add the new Rows number to it.
