Counting distinct occurences between two columns based on date

Hi All,

I'm using the below formula to try and calculate count of dates that are older than 90 days old between two columns (AK and AM). I want to make sure that should the value in AK AND the value in AM both be older than 90 days, they are only counted once.

<code>
Code:
=SUMPRODUCT(--('sheet1'!$B:$B="THC"),--('sheet1'!$AK:$AK<=TODAY()-90),--('sheet1'!$AM:$AM<=TODAY()-90),--('sheet1'!$E:$E={"1, THC Pilot","1, Both Pilot","2, THC Pilot","2, Both Pilot","3, THC Pilot","3, Both Pilot"}))
</code>
Can anyone assist?

Cheers,

STF

Why does 9 mean SUM in SUBTOTAL?
It is because Sum is the 9th alphabetically in Average, Count, CountA, Max, Min, Product, StDev.S, StDev.P, Sum, VAR.S, VAR.P.
Any ideas?

I'm getting a #value ! error with the current formula.

I'm trying to count all the dates in column AM and AK that are older than 90 days and also have "THC" marked in column B and one of {"1, THC Pilot","1, Both Pilot","2, THC Pilot","2, Both Pilot","3, THC Pilot","3, Both Pilot"} in column E.

thanks!

Any ideas?
I would strongly recommend not using whole column references in a formula like this. You are asking for a very large number of calculations.

In my suggestion below, I have only used down to row 15 for testing, but instead choose a number big enough to cover the largest data you might have but not too huge. (eg 5000?)

Try a formula like this

Code:
=SUMPRODUCT(--(B2:B15="THC"),--(AK2:AK15<=TODAY()-90),--(AM2:AM15<=TODAY()-90),--ISNUMBER(SEARCH("|"&E2:E15&"|","|1, THC Pilot|1, Both Pilot|2, THC Pilot|2, Both Pilot|3, THC Pilot|3, Both Pilot|")))

Thanks! Would you mind explaining the last piece of the formula? I'm not quite following.

I assume that you mean the blue part below.
Rich (BB code):
=SUMPRODUCT(--(B2:B15="THC"),--(AK2:AK15<=TODAY()-90),--(AM2:AM15<=TODAY()-90),--ISNUMBER(SEARCH("|"&E2:E15&"|","|1, THC Pilot|1, Both Pilot|2, THC Pilot|2, Both Pilot|3, THC Pilot|3, Both Pilot|")))

It checks your extra requirement:
.. one of {"1, THC Pilot","1, Both Pilot","2, THC Pilot","2, Both Pilot","3, THC Pilot","3, Both Pilot"} in column E
It does so by joining all of those values in one string, delimited by the "|" (any character not in the list of values) so we get a single string:
"|1, THC Pilot|1, Both Pilot|2, THC Pilot|2, Both Pilot|3, THC Pilot|3, Both Pilot|"
The formula then puts the "|" character before and after each value in column E and checks to see if it can find those values in the string.
For example,
- if E2 is "2, THC Pilot" the formula would look (SEARCH) for "|2, THC Pilot|" in the red string above. That string is found starting at position 28 in the red string so the SEARCH function returns 28. So ISNUMBER is true so row 2 would be included in the count.
- if E3 is "abc" the formula would look (SEARCH) for "|abc|" in the red string above. It is not found so SEARCH returns an error so ISNUMBER is false so row 3 would not be included in the count.

Hope that clarifies for you (it's usually easier to write the formulas than explain them :)).

Thanks! I don't think the formula is quite doing what I want it to.

Here is what the output should return:

I can't see how this relates to your original formula & description at all. :confused:

Any ideas? Hoping to get this working soon :(

Also tried to simplify but still not working
Code:
=SUMPRODUCT(--(B2:B15="THC"),--(AK2:AK15<=TODAY()-90),--(AM2:AM15<=TODAY()-90),[COLOR=#0000CD]--(E2:E15="*Pilot*")))[/COLOR]

Also tried
Code:
=SUMPRODUCT(--(ISNUMBER(SEARCH("THC",$B:$B))),--(ISNUMBER(SEARCH("*Pilot*",$E:$E))),--($AK:$AK>0),--(DATEDIF($AK:$AK,TODAY(),"d")+1<90),--($AMO:$AM>0),--(DATEDIF($AM:$AM,TODAY(),"d")+1<90))

But am getting # value error
