I have a summary page that pulls from multiple worksheet tabs, call them 1, 2
and 3. On the summary page I want to sum specific cells on a tab, say cell
a1,a2,a3. Can I on the summary sheet make a formula that will sum those
cells, but be flexible enough to recognize what tab I want summed by
referencing another cell on the summary page? In other words if I put 1 in
cell a1 on the summary sheet it will know to go to worksheet 1 and sum the
right cells, and if I put 2 in A1 it will know to sum those cells on
worksheet 2?
