Hi

Last post seems to have disappeared so I'll try again.

In B2:B50 I have dates in the format 27/11/2008. The last date being
31/12/08
In F2:F50 I have £ totals.

There are more than one instance of many dates.
In L2:L36 I have consecutive dates from 27/11/2008 to 31/12/08

I am using the following to acquire the totals for each day but it is
failing, it returns 0 for all entries.

=SUMPRODUCT(--($B$2:$B$50=L2),--($F$2:$F$50))

Help appreciated
Sandy
