ISBLANK to make an IF function work.

Hi all,

The below formula is doing the opposite to what I want.

=IF(R2<='Stock Level'!R2,S2,0)*AND(ISBLANK(P2))

Basically if cell p2 is blank I don't want the if function to work.

Hi,

I'm not entirely sure, but is this what you need?

=IF(ISBLANK(P2),"",IF(R2<='Stock Level'!R2,S2,0))

Cheers Dave, works a treat.... although i've found another problem.

I need the formula to also not work (add another condition) so that it will identify previous sheets within the workbook (labelled as a date dd.mm.yy 01.07.09, 02.07.09 etc) and take away mulitples of 15.... i have set a minimum re-order level of 15 units. So an order can only go through if there is over 15 units needed. I think i'm losing here... might need to get some VBA advice on this one....

The workbook I'm using is found here (See test sheet zip file...)
