SUM of a range conditional on date

[bdw248]

I've got 15 columns, A/c No, Description, Jan, Feb, Mar etc and YTD.
I'm wanting to sum the columns conditional to a date, ie sum(C:E)
when the date is 31/03/04.
I've been using if statements but am limited by the maximum of 7 if's
(I need 12).
I'm open to any suggestions,

Thanks

Bria

Hi

Maybe you are somewhat more specific. Which columns you want to sum. And how
is the date you mentioned related with data in columns to sum.

A general idea - you can sum every month separately, with some logical
conditions controlling which column is taken into account. Something like
=LogicalExpr1*SUM(Jan)+LogicalExpr2*SUM(Feb)+...+LogicalExpr12*SUM(Dec)
or
=LogicalExpr1*SUMIF(Jan,Condition)+LogicalExpr2*SUM(Feb,Condition)+...+Logic
alExpr12*SUM(Dec,Condition)
