When I responded, I didn't realize that you were the OP. I didn't check the username...I just assumed it was someone else. Sorry!
What I said about VLOOKUP still stands, but I would have said it differently had I realized that it was you that responded.
That said, we'd like to help, so maybe we're just missing a piece of information or two that explains what you are trying to do.
For example, if an IF with VLOOKUP is required, tells us what you are looking up and what the IF criteria and results should be.
If you just want to see what an IF and VLOOKUP formula might look like, Google IF VLOOKUP for lots of different combinations/examples. Perhaps that will get you started.
