The data is not always going to be in E6, depends on the month working left
to right which means F6 is April, G6 is May and so on.

The calculation will always be current - previous year. And when 2009 comes
into play, the plan is to duplicate calculating 2009-2008 for current and
previous month data.

Well, at least we are getting somewhere. But we need more information.

How do you know when to use the current month, and when to use the previous
month?

If it's the current month, what data do you want to pick up? Is it always
E6? Or is the column dependent on the month?

What calculation do you want to perform. Is it always the current year
(2008) less the previous year?

What happens when 2009 comes along?

Fred.

Thanks for quick reply and my apologies for not being clear. Just driving
me
nuts...
The months are always going to be current month and a month behind due to
data not being available. Not sure if that explains my needs. But I also
would not reference a certain row because the spreadsheet months are
entered
column beside column. Other than having to go in and change the formula
to
reference current month. Was hoping there was a way to skip that.

Your requirement isn't clear to me, but hopefully the following hints
will
help you find your answer.

The current month is =month(today())
The previous month is =month(today())-1

Your formula has several problems with it.
First, your If statement doesn't say what to do when the condition is
false.
Second, you never have to use And with True. True will always be true. So
you can simplify your statement to:
=IF(MONTH(TODAY()),SOURCE_2008!E6-SOURCE_2007!E6)
Third, you're not testing the month for anything. What should the month
equal?

Hi -
Working with (2)spreadsheets: 2008 and 2007 for comparison. Need
assistance
with writing formula to recognize on 2008 spreadsheet to calculate
"previous"
month, current if there is no data for "current" month. Right now I
have:
=IF(AND(MONTH(TODAY()),TRUE),SOURCE_2008!E6-SOURCE_2007!E6) whereas
it's
looking in a specific cell, which I rather not. Is this possible?
Some
columns report "current" data and others "previous".
