I need to write a formula for cells F2:Q2 that calculate the following:

For example - in cell F2

If F1 = A2 then F2=D3 + If F1 = B2 then F2=D3 = If F1 = C3 then F2=D3

So, let's say Cells A2:C2 all contained "Jan", then cell F2 would equal "9". On the other hand, based on the current values of cells A2:C:2, cell a2=3, g2=3, and h2=3.

Let me know if I need to clarify as I am aware this may seem confusing.

Thanks!
