I am using the attached formula, but need to modify it to within a range.
Here is the existing formula:

Formula =IF((M2-L20),(ROUND(((M2-L2)*1440),0))," ")
I need to have the first IF statement to me like this, where MaxTAT=180
(for now):

Revision =IF((MaxTATM2-L20),(ROUND(((M2-L2)*1440),0))," ") I want the
formula to round the answer if M2-L2 is between 0 and 180, or leave it blank
if not. When I put the formula in as this, it appears to only consider the
M2-L20 part of the formula. Am I missing something REALLY basic here?

Thanks for any help. Bill in Northern California
