I am keeping track of our school's jog-a-thon with Excel. I have created a
workbook, where every worksheet is a classroom. At the bottom of each
worksheet I have a cell that has a formula adds all the money up for that
class.

The last worksheet page is a totals page. What formula do I put in the
cells to get the information from the other worksheet pages? Is there a
formula that I can put in there, so that it will update when we enter new
information in the worksheet pages?
