You just forgot to include the SUM for your second function:

=SUM(H2:H3)/SUM(E2:E3)

I basically just want to divide the sum of one range of cells by the sum of
another range of cells.

This works: =SUM(H2+H3)/(E2+E3).
This does not work: =SUM(H2:H3)/(E2:E3)

I want to be able to copy the formula to continue adding to the range of
cells on each side.

IE: =SUM(H2:H4)/(E2:E4) through end of spreadsheet: =SUM(H52:H54)/(E52:E54)


What's wrong with my formula?
