Hi,
I'm trying to use the VLOOKUP formula as the argument inside an IF formula.
I'm doing this because my VLOOKUP references a different file that has
30,000 rows in it, and that seems to be making my VLOOKUP fail due to lack of
system resources.
Anyway, here is how I am trying my IF statement:

=IF(A120000, =VLOOKUP(A1, etc, etc...,FALSE),VLOOKUP(A1, etc, etc...,FALSE))

My IF statement is using two different VLOOKUP functions as arguments, so
that I can look up data in two unique source files.

But, my IF statement returns an error if I do this. Any thoughts? I tried
adding parenthesese, also double-quotes, but I can't get it to work.
Thanks....
