retrieve unique items with 2 criteria
 

I've been using the following formula from the xldynamic website detailing
sumproduct usage as a base for retrieving uniqe instances in a data series.
I've been trying to modify the formula to allow me to utilize one additional
criteria.
Original formula:
=SUMPRODUCT((A1:A20<"")/COUNTIF(A1:A20,A1:A20&""))

Here is my formula:
=SUMPRODUCT((($O$7:$O$2710<"")*($M$7:$M$2710="198 6"))/COUNTIF($O$7:$O$2710,$O$7:$O$2710&""))

I'm trying to say how many unique instances are there for column O, where
column m = "1986?" Not sure what I'm doing wrong but help would be
appreciated.

tia,
Dave


This seems to apply only the second criteria

retrieve unique items with 2 criteria
 

You don't need an argument for the "O array", try:

=SUMPRODUCT((($O$7:$O$2710)*($M$7:$M$2710="1986"))/COUNTIF($O$7:$O$2710,$O$7:$O$2710&""))

This gives me the #value error. Any other thoughts?
I thought the O qualifier was safeguarding against blank cells?

Dave,

You could use

=SUM(--(FREQUENCY(IF(M7:M2710=1986,MATCH(O7:O2710,O7:O271 0,0)),ROW(INDIRECT(
"1:"&ROWS(O7:O2710))))0))

which is an array formula, so commit with Ctrl-Shift-Enter

Thanks Bob - this worked.

Alright. Question answered but I've got another one. Of the unique values
in column O, I've been trying to apply the small function to the formula
below to give me the kth smallest value of the unique O column values. I've
tried a few positions including the following but have not had any luck:

=SMALL(--(FREQUENCY(IF(TRIM('prepay detail'!M7:M2710)=$B32,MATCH('prepay
detail'!O7:O2710,'prepay detail'!O7:O2710,0)),ROW(INDIRECT(
"1:"&ROWS('prepay detail'!O7:O2710))))0),1)

any thoughts?

Dave

Try...

=SMALL(IF((M7:M100=1986)*(MATCH(M7:M100&"#"&O7:O10 0,M7:M100&"#"&O7:O100,0
)=ROW(O7:O100)-ROW(O7)+1),O7:O100),2)

....confirmed with CONTROL+SHIFT+ENTER. Adjust the range accordingly.

Hope this helps!

You guys continue to impress. This is great.
I do have a couple of questions though.

If I understand this correctly, the match formula can have a lookup value as
an array instead of just a single value. If its lookup array and lookup value
are the same, then it is simply giving an array of the position of each item
in the total range used in the lookup value/lookup range.
It appears you've concatenated the 2 criteria columns for the purpose of
locating their commonalities in the array. This is intuitive looking back on
it but clever without knowing it. Was the "#" an arbitrary choice for a
connector? Why is it necessary to have any connector?

thanks to both Domenic and Bob for this one!

Dave

The "#" is used to deal with situations where you have...

1,11
11,1

Without "#"...

111
111

With "#"...

1#11
11#1

Note that you can use other characters as well for this purpose. For
example, you can also use "@".

Hope this helps!
