Okay I am try to sum up half a row and subtract away the other half of a
row. It is a coding scheme however and I want excel to ignore every time
there is a 99, so pretend it is a 0 in other words, but there is too
much data to change them all to 0. Thanks in advance for your help.

try:
=SUMIF(A1:H1,"<99",A1:H1)-SUMIF(I1:P1,"<99",I1:P1)
