Also question is, what is the difference between IF and IIF?

The critical difference between IIF (available from VS 2002 forward) and IF (available in VS 2005 forward) is that IIF is a function and evaluates all of its arguments prior to returning a value, while IF is an operator that executes like a short-circuiting conditional, only evaluating the true or false argument
