In cell B7 under the 2 use one of these and copy to B7
a) =SUMPRODUCT(--($A$1:$A$4$A$4-B6),B1:B4)/SUMPRODUCT(--($A$1:$A$4$A$4-B6)) b) =SUMIF($A$1:$A$4,""&$A$4-B6,B1:B4)/COUNTIF($A$1:$A$4,""&$A$4-B6) c) in XL2070 only =AVERAGEIF($A$1:$A$4,""&$A$4-B6,B1:B4) best wishes -- Bernard V Liengme Microsoft Excel MVP http://people.stfx.ca/bliengme remove caps from email "Kgov" wrote in message ...

A phrase like (A1:A44) returns an array of Boolean values such as {FALSE,
TRUE, TRUE, TRUE} When you perform an arithmetic operation on a Boolean, Excel treated TRUE as 1 and FALSE as zero A convenient thing to do is to double negate the values (change the sign and then change it again) - which means they stay the same but become numbers So --(A1:A44) would then give us {0,1,1,1} J.E McGimpsey is tell all at: http://mcgimpsey.com/excel/formulae/doubleneg.html best wishes -- Bernard V Liengme Microsoft Excel MVP http://people.stfx.ca/bliengme remove caps from email "Kgov" wrote in message ...
