SUMIF discontinuous cells

Attachment 613688

I want W6 formula to return SUM of MTL QTY values IF row 2 denotes "Notice to Proceed" in the paired columns........my current formula of =SUMIF([E2, G2, I2, K2, M2, O2, Q2, S2, U2], "Notice to Proceed", [E6,G6,I6,K6,M6,O6,Q6,S6,U6]) is not working. I tried both merging and unmerging my row 2 cells. I assumed the problem was discontinuous ranges for criteria and sum? Please help!
