Count unique text values based on condition in another column

[himihai]

Hello,

I need to count uniques text values in a column that contains names.
But I only need to count the unique values that are satisfying a condition in another column.

Example:

<TABLE style="WIDTH: 166pt; BORDER-COLLAPSE: collapse" cellSpacing=0 cellPadding=0 width=222 border=0><COLGROUP><COL style="WIDTH: 77pt; mso-width-source: userset; mso-width-alt: 3766" width=103><COL style="WIDTH: 89pt; mso-width-source: userset; mso-width-alt: 4352" width=119><TBODY><TR style="HEIGHT: 15pt" height=20><TD class=xl64 style="BORDER-RIGHT: windowtext 0.5pt solid; BORDER-TOP: windowtext 0.5pt solid; BORDER-LEFT: windowtext 0.5pt solid; WIDTH: 77pt; BORDER-BOTTOM: windowtext 0.5pt solid; HEIGHT: 15pt; BACKGROUND-COLOR: black" width=103 height=20>Group</TD><TD class=xl64 style="BORDER-RIGHT: windowtext 0.5pt solid; BORDER-TOP: windowtext 0.5pt solid; BORDER-LEFT: windowtext; WIDTH: 89pt; BORDER-BOTTOM: windowtext 0.5pt solid; BACKGROUND-COLOR: black" width=119>Name</TD></TR><TR style="HEIGHT: 15pt" height=20><TD class=xl63 style="BORDER-RIGHT: windowtext 0.5pt solid; BORDER-TOP: windowtext; BORDER-LEFT: windowtext 0.5pt solid; BORDER-BOTTOM: windowtext 0.5pt solid; HEIGHT: 15pt; BACKGROUND-COLOR: transparent" height=20>a</TD><TD class=xl63 style="BORDER-RIGHT: windowtext 0.5pt solid; BORDER-TOP: windowtext; BORDER-LEFT: windowtext; BORDER-BOTTOM: windowtext 0.5pt solid; BACKGROUND-COLOR: transparent">Name 1</TD></TR><TR style="HEIGHT: 15pt" height=20><TD class=xl63 style="BORDER-RIGHT: windowtext 0.5pt solid; BORDER-TOP: windowtext; BORDER-LEFT: windowtext 0.5pt solid; BORDER-BOTTOM: windowtext 0.5pt solid; HEIGHT: 15pt; BACKGROUND-COLOR: transparent" height=20>a</TD><TD class=xl63 style="BORDER-RIGHT: windowtext 0.5pt solid; BORDER-TOP: windowtext; BORDER-LEFT: windowtext; BORDER-BOTTOM: windowtext 0.5pt solid; BACKGROUND-COLOR: transparent">Name 1</TD></TR><TR style="HEIGHT: 15pt" height=20><TD class=xl63 style="BORDER-RIGHT: windowtext 0.5pt solid; BORDER-TOP: windowtext; BORDER-LEFT: windowtext 0.5pt solid; BORDER-BOTTOM: windowtext 0.5pt solid; HEIGHT: 15pt; BACKGROUND-COLOR: transparent" height=20>a</TD><TD class=xl63 style="BORDER-RIGHT: windowtext 0.5pt solid; BORDER-TOP: windowtext; BORDER-LEFT: windowtext; BORDER-BOTTOM: windowtext 0.5pt solid; BACKGROUND-COLOR: transparent">Name 2</TD></TR><TR style="HEIGHT: 15pt" height=20><TD class=xl63 style="BORDER-RIGHT: windowtext 0.5pt solid; BORDER-TOP: windowtext; BORDER-LEFT: windowtext 0.5pt solid; BORDER-BOTTOM: windowtext 0.5pt solid; HEIGHT: 15pt; BACKGROUND-COLOR: transparent" height=20>a</TD><TD class=xl63 style="BORDER-RIGHT: windowtext 0.5pt solid; BORDER-TOP: windowtext; BORDER-LEFT: windowtext; BORDER-BOTTOM: windowtext 0.5pt solid; BACKGROUND-COLOR: transparent">Name 2</TD></TR><TR style="HEIGHT: 15pt" height=20><TD class=xl63 style="BORDER-RIGHT: windowtext 0.5pt solid; BORDER-TOP: windowtext; BORDER-LEFT: windowtext 0.5pt solid; BORDER-BOTTOM: windowtext 0.5pt solid; HEIGHT: 15pt; BACKGROUND-COLOR: transparent" height=20>b</TD><TD class=xl63 style="BORDER-RIGHT: windowtext 0.5pt solid; BORDER-TOP: windowtext; BORDER-LEFT: windowtext; BORDER-BOTTOM: windowtext 0.5pt solid; BACKGROUND-COLOR: transparent">Name 1</TD></TR><TR style="HEIGHT: 15pt" height=20><TD class=xl63 style="BORDER-RIGHT: windowtext 0.5pt solid; BORDER-TOP: windowtext; BORDER-LEFT: windowtext 0.5pt solid; BORDER-BOTTOM: windowtext 0.5pt solid; HEIGHT: 15pt; BACKGROUND-COLOR: transparent" height=20>b</TD><TD class=xl63 style="BORDER-RIGHT: windowtext 0.5pt solid; BORDER-TOP: windowtext; BORDER-LEFT: windowtext; BORDER-BOTTOM: windowtext 0.5pt solid; BACKGROUND-COLOR: transparent">Name 2</TD></TR><TR style="HEIGHT: 15pt" height=20><TD class=xl63 style="BORDER-RIGHT: windowtext 0.5pt solid; BORDER-TOP: windowtext; BORDER-LEFT: windowtext 0.5pt solid; BORDER-BOTTOM: windowtext 0.5pt solid; HEIGHT: 15pt; BACKGROUND-COLOR: transparent" height=20>b</TD><TD class=xl63 style="BORDER-RIGHT: windowtext 0.5pt solid; BORDER-TOP: windowtext; BORDER-LEFT: windowtext; BORDER-BOTTOM: windowtext 0.5pt solid; BACKGROUND-COLOR: transparent">Name 3</TD></TR><TR style="HEIGHT: 15pt" height=20><TD class=xl63 style="BORDER-RIGHT: windowtext 0.5pt solid; BORDER-TOP: windowtext; BORDER-LEFT: windowtext 0.5pt solid; BORDER-BOTTOM: windowtext 0.5pt solid; HEIGHT: 15pt; BACKGROUND-COLOR: transparent" height=20>c</TD><TD class=xl63 style="BORDER-RIGHT: windowtext 0.5pt solid; BORDER-TOP: windowtext; BORDER-LEFT: windowtext; BORDER-BOTTOM: windowtext 0.5pt solid; BACKGROUND-COLOR: transparent">Name 4</TD></TR></TBODY></TABLE>

So I need to count unique names from group "a"

I already got the formula for counting the unique values from the whole list, and I just need to add the condition that would restrict the search only to one group (condition).

Any ideas?

I pasted then pressed control shift enter,but was still told there was an error in the formula. Am i doing something wrong with the ctrl+shift+enter part?

Control+shift+enter: Press down the control and the shift keys at the same time while you hit the enter key. If done correctly, Excel itself puts a pair of { and } around the formula in recognition.
