I'm hoping someone can help with the following...

I tried checking the SUMIF and SUMPRODUCT archives with no success.
Maybe I am not using the correct function.

Here is my current formula

=SUMIF(M2680.001,(AND(sum(BS268+BT268-BU2680,BS268+BT268-
BU268),*AZ268*(1-BF268))))

What I want is if the first 2 conditions are met
M268 .001 and
BS268+BT268-BU268 0
then I want the sum of
BS268+BT268+BU268
if not then I want
AZ268*(1-BF268)

Any help would be greatly appreciated!
