C3 has "1139.28" G1 = "400.00" G2= "280.00" G3 = "65.00" G4 =" 206.52"
G5="38.5" so therefore, G1:G5 = 990.02, and 1139.28-990.02=149.26.

I tried all of the formatting suggestions, every cell is now formatted as
number.

What is your data in C3 and in G1:G5?

Are G1:G5 formatted as Text? If so, the SUM function won't recognize them.
Try formatting as Number or General.

How is the cell formatted where you are entering the formula? Try changing
it to "General" and see what happens.

Are Automatic Calculations turned on?
TOOLS--OPTIONS--CALCULATION Tab--Check "Automatic"

Try writing it like this:

=C3-SUM(G1:G5)

my formula says =sum(C3-(G1:G5))
It comes up and says 0, when it should say 149.26
