How many values appear more than once in a range?

Could someone help me out on this, please?

I have a single column range as a defined name (rngPlaces).

I want a formula in another cell to count how many values (text) appear
more than once in the range.

So...
- Values that appears only once in the list: Don't count.
- Values that appears more than once in the list: Count the value as 1.
- Blank cells: Don't count.

To further clarify - a value that appears multiple times is only
counted once.

- "Mexico City" appears 50 times: "Mexico City" counted as 1
- "Paris" appears 2 times: "Paris" counted as 1
- "Denver" appears 1 time: "Denver" counted as 0

Any ideas?

Excel 2002.

Thanks.

Hi Bruce,

=COUNTIF(A\$2:A9,A9)
=COUNTIF(rngPlaces,"Mexico City")

=(COUNTIF(rngPlaces,"Mexico City")1)+0

Bruce,

Array enter (enter using Ctrl-Shift-Enter)

=SUM(IF(1/COUNTIF(rngPlaces,rngPlaces)<1,1/COUNTIF(rngPlaces,rngPlaces),0))

will work as long as rngPlaces isn't a complete column (must be less than
65536 cells long)

Perhaps try, array-entered (CTRL+SHIFT+ENTER):

=SUM(IF(LEN(rngPlaces)0,1/COUNTIF(rngPlaces,rngPlaces)))-SUM(--(COUNTIF(rng
Places,rngPlaces)=1))

Another alternative,

You didn't test this with the OP's specs in mind. If the OP's range contains
blanks (and since the OP explicitly mentions this case, whatcha suppose the
odds are that there will be some blank cells?), your formula returns #DIV/0!

Hmmm. I see what your formulas do, but was looking more to answer this
question...
"How many cities in the list appear more than once?"

So, I don't want to only count "Mexico City", but any and all cities that
appear more than once. Again, I'm looking for a formula in one cell to do
this. I know I can put a special countif in an additional column within each
record then sum that up or whatever. But I'm hoping for one formula to do
it.

Any thoughts?

Hi Bruce,

=COUNTIF(A\$2:A9,A9)
=COUNTIF(rngPlaces,"Mexico City")

=(COUNTIF(rngPlaces,"Mexico City")1)+0

Oh, that was soooo close, but like Harlan points out, I do have some blanks
involved. Bummer.

Maybe there's no way to do this with just a formula?

Brilliant. That seems to work great. I don't understand it, but it works.

What is the "--" for in the syntax?

Maybe you can look at my other question,
"How to CountIf Involving Another Column"?

Thanks a bunch for your time!!

That works too! Thanks, Harlan. I have to admit, I'm more used to Sumproduct
functions. Can you see any advantage to yours over the one Max offered?

Would you mind looking at my other question,
"How to countif involving another column"?

Thanks for all your time, Harlan.
