Count unique value comparing multiple coloumn

[pratheesh1983]

Hello,

I have a table which has two columns, column A & B - Column A have "section" and B consists of User Name. In column B user column the entries will be repeating. I need a formula which will give me the count of unique value base on the section (ref. Table 2) eg. for Section A = no. of unique value is 4. Could any one please assist me to formulate formula for this?




Table 1

SECTION	USER
A	RAMESH T K
A	RAMESH T K
A	ARUN M
A	ARUN M
A	MATHEW W
A	MATHEW P
B	PAUL PK
B	PAUL PK
B	TOM LG
C	TOM LG
C	ASHISH N
C	PARTRICK P

<colgroup><col><col></colgroup><tbody>
</tbody>

Table 2

UNIQUE VALUE
SECTION	COUNT
A	4
B	2
C	3

<colgroup><col><col></colgroup><tbody>
</tbody>

Array formula in E3 copied down
=SUM(IF(FREQUENCY(IF(A$2:A$13=D3,MATCH(B$2:B$13,B$2:B$13,0)),ROW(B$2:B$13)-ROW(B$2)+1),1))

Another option with "regular" formula
