Hello Rob
Not sure but try:

Here is the formula for the cell2, cell3

Cell2 = 03/15/07
cell3 =

=IF(A18=" "," ",IF('Loan Summary'!$B$7,DATE(YEAR('Amortization
Schedule'!B17),MONTH('Amortization Schedule'!B17),DAY('Amortization
Schedule'!B17)+14),DATE(YEAR('Amortization
Schedule'!B17),MONTH('Amortization
Schedule'!B17)+1,DAY('Amortization Schedule'!B17))))

Try it with a little coercion:
=DATEDIF(A1+0,B1+0, "d")
assuming source dates in A1, B1 (earlier/later dates)

I using DATE(Cell1,Cell2,"d"), the result is always 0.

I used the evalute forumula and here is what it says :

Datedif(39236,39266, "d"). How can the result be 0. Cell1 and Cell2
are
calculated fields with a format of custom (mmm dd yyyyy). I have tried
changing the format to date but still the same effect.

The calculations in the cell1 and cell2 are Date(Year(cell5),
Month(cell5)+1, Day(cell6).

Help - this is driving me crazy.
