Thank you to the both of you I'll try it with dates.

Didn't mean to 'dis' you Duke by re-posting but when I couldn't get it to
work and was pretty desparate to finish it today I thought that you might be
tucked up in bed so osted again. I thought it must be something to do with
formats as I managed to get a test array with other data in it to work.

Once again thanks

About the only practical way you can keep the first column as text & make
this work is if you put the year first, i.e., 2004-07. Then you can use the
formula I gave you yesterday. However, I agree with Bob that using actual
date values is better & easier than working with text values

I need to sum the values from an array based on an input in a cell. The
table looks like below

A B

Month PT Basic
Hours Paid

07-2004
08-2004 50
09-2004 100
10-2004 50
11-2004 50
12-2004 50
01-2005
02-2005 75
03-2005
04-2005
05-2005

I want to enter 10-2004 in an input cell and then a formula to return the
sum of hours in previous months ie 150. Another formula should then return
mth 10-2004 and any following ie 225.

I have tried =SUM(IF(month<G2,basic_hours)) as an array fomula, where G2 is
the cell I entered 10-2004 in but keep getting zero. A is formatted as text
as is G2

A previous reply did not work.

Thanks for any help
