IF statement with IFDATED statement

[smazza]

I'm trying to write a formula & it keeps saying that my formula is incorrect. I want to say if there is a value in cell A1, then calculate the months between A1 & B2, otherwise, leave blank. Here is what I have been writing that keeps coming back incorrect.

=IF(A1>0,(=DATEDIF(A1,A2,"m")),"")

A1 is in date format which might be the problem, but I don't know what else to put.

The date format is not the issue, it's the middle DATEDIF statement because when I use the fx button, that the only part that comes up "Ilogical."
