Formula counts incorrectly

was · #1 06-14-2005, 06:30 PM

Help please.
Column K contains dates and blank cells. I would like to count how many of these dates fall within a given date range. For example, in the first week in May. Column K contains these dates. 5/2/2005, 5/3/2005, 5/5/2005, 5/5/2005. I would like to count this as 4 dates within the first week of May. I created this formula but the output is 3.

=SUMPRODUCT(--(ECNT!F2:F515>=DATE(2005,5,2)),--(ECNT!F2:F515<=DATE(2005,5,6)),--(ISNUMBER(ECNT!K2:K515)))

I assume that it is only counting 5/5/2005 one time?

I changed the dates in the formula to check a second 2nd date range (5/9 to 5/13). Column K contains only one date within that range 5/13/2005. However this formula returns 2.

Could someone please modify this formula to work the way I want it to?

It workes fine for me:.

=SUMPRODUCT((A2:A10>=DATE(2005,5,2))*(A2:A10<=DATE(2005,5,6))*(ISNUMBER(B2:B10)))
---> 4

Hope it helped

Quick question your write up talks about column K only
your equation shows Column F
What is the is number section for?
