=IF(AND(O1=0,P1=0),0,IF(P1<0,IF(O10,O1/P1,"")),"percentage change is
infinite")

You will realise, I hope, that if P1 and O1 are 2008 and 2009 sales data,
=O1/P1 does *not* show the percentage increase or decrease. If you want the
percentage increase or decrease you need =O1/P1-1.

Thanks, but I have found when I enter amount in column o i still get
the #div?0! message.

eg


=IF(AND(O1=0,P1=0),0,IF(O10,O1/P1,""))

and format accordingly

Hi, First post. I have 2009 sales data in column O and 2008 sales
data column P and the the following formula in column Q = O1/P1 as
have formatted it as a % to show an increase or decease

When the sales data in column o is 0 and p is 0 the result is
#DIV/0!
When the sales data in column o is 0 and p is 0 the result is a %

I want the workbook to display a % when column o is 0

If both 0 & P are 0 i want a 0 to be displayed

I appreciate you help

Thanks
