Create two new worksheets--one to the far right and one to the far left.

Call them Start and End

Then using a sheet (Summary) that is outside this "sandwich" of worksheets:

=sum(start:end!B37)

Then you can drag sheets in and out of that sandwich to play what if games.

I'd put a couple of notes on each of these sheets:

"don't delete this sheet!"

And protect the worksheet so that people don't use it for real data.

I have a workbook with 12 worksheets and I need to sum 1 cell (ex. B37) on
each worksheet on one summary page. How can I track the cell from the
different worksheets to add them?
