Hi
try this =IF(D1="z",A1+10,IF(D1="y",A1+20,"")) , you can copy down the column.

I'm looking for help with a conditional formula.

A B C D
1 11/1/09 z

I'd like a formula in column B to calculate days depending on columns A and
D. If column D is "z", i'd like to add 10 days to column A. If column D is
"y", I'd like to add 20 days to column A.

Thanks for any assistance!
