Networkdays

2-----03/03/05---05/05/05----=NETWORKDAYS($A2,$B2) = GIVES ANSWER -3


I have a spreadsheet in which I would like to calculate Networkdays between two dates, it works in row 2, but if I alter the formula in row one so a figure only shows in C1 if there are dates in A1 and B1 I get a "TRUE" value instead of 3. Is it possible for the correct Networkday value of 3 to show in row C1? Hope it makes sense.

My mistake, i found out my error.


the formula works with the OR value taken out


=IF($A1*$B1=0,"",NETWORKDAYS($A1,$B1))
