Here's my formula, but it is resulting unexpected.

=IF((NETWORKDAYS(A68,D68))=1,1,"")

I want to eliminate 'same day'. So if the date is 1/1/06 in A68 and 1/1/06
in D68, I don't want a number but rather a blank. My formula indicates 1
when it sees same day.

The formula works correctly if cell A has 1/1/06 and cell d has 1/2/06 = 1

Thanks!
