I figure this should be a simple one for y'all experts. I want to calculate months between two dates, similar to the DATEDIF function in excel. And if there is a way to include an IF-THEN function so that it doesn't give me a negative number if the second date is missing, even better. Thanks

Here it comes

code:

Case ( not IsEmpty (dat1), Month(dat2)-Month(dat1)+12*(Year(dat2)-Year(dat1)))

I appreciate the quick response. Allow me to show my ignorance here. Where do I enter this formula. I tried creating a calculation field and entering it there, but my values are way off. (ex. 5-28-1998 to 10-1-1998 is -9281, 6-30-1998 to 1-8-1999 gives 53279). thanks

Just make sure that dat1 and dat2 are of type "date", and the result of calculation is number.
