Hi
the formula returns 1 if both conditionas are met or 0 if not both
conditionas are met. So your right. 1 is the tRUE part of the second IF
formula and '0' the FALSE part.

You may take a look at the following site for an alternative approach using
sUMPRODUCT:

Excel 2000 ... I attempted to write the following array
formula free-hand & failed ... Consequently, I used
Conditional Sum Wizard to build formula for me.

Above said ... Can one of you Excel Magicians interpret
(in plain English) how end of this formula works?

=SUM(IF($M$2:$M$12000=$BG2,IF($T$2:$T$12000=0,1,0) ,0))

,1,0),0))

What do last 3 positions & characters stand for? I am
pretty certain the 1st 1,0) is part of 2nd IF Function,
but have no idea how formula is working.

Thanks ... Kha
