Jim, thanks...but I have the problem when it is on a range...and I need it to
be on a range....an limiting dates. I have counted the days in a range, but
it dobles count when a day is repeated. my formula was like this:

=DCOUNT(ECXCFIFUT, "Total Volume", $H$52:$I$53)
where h52-i53 is the date conditional. and total volume is what I wanted to
count...I could replace total volume with action date in the example of my
original question. and with the date conditional...the answer would be 4
instead of 3 because 1-sep would be double counted.


I was trying to use "match" and "frequency" but I could't do it
thanks

imagine a range like this:

Actiondate volume
1-sep 2
1-sep 3
3-sep 5
5-sep 7
9-sep 6
etc

this constrains
Actiondate Actiondate
=1-sep <6-sep



I would like a function that counts the number of days between my contrain
that do not doble count de dates....in this example the answer would be 3

Thank you people very much....I am so gratefull for your help
