I didn't have a look at your exact formula, so I'll give a somewhat abstract form
=IF(Kx="C",formula(Nx);formula(Lx))
With formula(Y) being a formula or a function using cell Y.
Hope this helps

I am trying to figure out how to format an IF equation for the following:
I want column Q (Average) to be the average of column O (Eta MOS), Column P (GFS MOS)and then either column L (850 tmp high) or column N (with clouds. What I want to do is have the program look at column K (sky cover) and from that, determine whether to average in column L or column N.
In other words, I want it to say IF(column K is C, MC, R, S, TSTM) then use column N, else use column L.
Can this be done in excel? If so, can anyone help with how?
Thank you.
