Problem with counting

Folks,
In Column A of the attached workbook I have various IP addresses, some with one to three "xxx". In D3:D5 I have an array formula using SUM, MID, COLUMN functions.

I'm not getting the expected results. I am wanting to know how many IP address's have one "x", two, "xx" and three "xxx". I get the three "xxx" but that all.

The cells are formatted as General. Try formatting the cells you are test as Text.  I think they need to be formatted as Text for MID, LEFT and RIGHT to work.

I changed the formatting to text but the results were the same.
By the way I am not using RIGHT but I am using COLUMN

I don't know. You are using Array formulas and I have not used these.

Why not use COUNTIF with wildcards?

=COUNTIF(A:A,"*xxx*")           count of cells containing xxx
=COUNTIF(A:A,"*xx*") - K2     count of cells containing xx     (K2 is count above)
=COUNTIF(A:A,"*x*") -SUM(K2:K3)       count of cells containing x   (K2 & K3 are counts above)

Thinkpads_User,
If you change the format of a cell, it does not change the contents of that cell. If they were originally numbers, changing the format to text does not make those cells contain text. And vice-versa.

The array formulas were double or triple counting cells when looking for "xx" or "x". This is because they were getting substrings from the cell starting at each possible position. So a cell containing "xxx" would trigger two "xx" counts--one for the first two x and the second for the last two.

Similarly, a count for "x" would be triggered three times in a cell containing "xxx" and twice in one containing "xx".

COUNTIF only counts a cell once, no matter how many times the pattern is matched. What's more, you don't need to array-enter the formula.

Brad,
Thanks for the explanation. Why didn't I use COUNTIF? Let's just say I had another senior moment and then I wanted to experiment more with using arrays.
Great solution - great job!

fh_freese,
If you really want to use an array formula, consider one like this to find the number of cells containing "x" (but not "xx" or "xxx"):
=SUM(ISNUMBER(SEARCH("x",A2:A11)) - ISNUMBER(SEARCH("xx",A2:A11)))
