hello,
By using the sumproduct formula I'm trying to sum all the dates that are within March.
,--('DATA MARCH 2010'!$Q$1:$Q$1000>=DATE(2010,3,1)),--('DATA MARCH 2010'!$Q$1:$Q$1000<=DATE(2010,3,31))
Colomn Q is full with dates. When I use this formula I get 0 as result. Manually I add a date lik 15 March 2010.
Does somebody knows the solution?
Thanks!
