I have a sum in one sheet that references data in another sheet.
i.e. =IF($C8='Sheet 2'!$A$5'Sheet2'!$B$5 (it is a lot bigger than this with
IF OR in it so please dont pull me up on the sum part)

The sum is in Sheet 1 cell F8. As can be seen from the sum, if cell C8 on
sheet 1 equals the value of cell A5 in sheet 2, return the value of Cell B5
in sheet 2. The sum works fine, however, if I insert a row in sheet 2, the
sum references on sheet 1 change.
So, if I insert a row in sheet 2 above cell A5, my sum on sheet 1 changes to
$A$6.

My question here is is it possible to disable something in excel so that the
cell reference does not update if changes are made in sheet 2.
I always thoughts as long as the dollar sign was in the sum, the sum would
never change.
