I have a column of names related by a column of numbers corresponding to each name. Each name is connected to a number and the same number can repeat. I want to count how many times a name occurs removing duplicates.
Counting unique rows

Here is an example of the problem

Hello,
Attached is your test file
Hope this will help

Would VBA solution be acceptable?

Yes it would

OK, I assume that all the colours in column B will have a number in column C and you are looking for a result that will give counts of each unique colour/number combinations. Is that correct?

Yes

Re,
Is the formula in Message # 4 producing your expected result ... or not ?

Unfortunately not

Do you mind explaining why ....

When I applied this formula to a large data set it returned 0, could be because it only works for manually selected rows

1. Have you adjusted the ranges to their actual sizes ...?
2. Have you noticed in cell G2 ... the word Blue ... cannot be written Blue :

2. Have you noticed in cell G2 ... the word Blue ... cannot be written Blue :
1. I adjusted the ranges and I still receive 0, it only works on a small data set
2. No I haven't, I'm not sure why it can't be written like that

2. No I haven't, I'm not sure why it can't be written like that
The word in the reference cell G2 must be written exactly in the same way as it appears in your list ... in order to be correctly identified ...

Looks like the *(B1:B10=G2) part of the formula is returning 0 for all values even for the value in G2

Looks like the *(B1:B10=G2) part of the formula is returning 0 for all values even for the value in G2
If you highlight exactly this portion (B1:B10=G2)
and Hit F9 to evaluate ...
you should see : {FALSE;FALSE;TRUE;FALSE;FALSE;TRUE;FALSE;TRUE;FALSE;TRUE}

If you highlight exactly this portion (B1:B10=G2)
and Hit F9 to evaluate ...
you should see : {FALSE;FALSE;TRUE;FALSE;FALSE;TRUE;FALSE;TRUE;FALSE;TRUE}
Then for my data set the return values are all false when selecting rows A1:A34538. The value I am looking for occurs 8 times within the column with duplicates. I replaced G2 with the value I am looking for using the same format.

Try this, click the button on the sheet to display counts
Code assigned to the button is
Code Sub UniqueCounts()
 Dim x, y, e, i As Long, oDic1 As Object, oDic2 As Object
 Set oDic1 = CreateObject("scripting.dictionary")
 Set oDic2 = CreateObject("scripting.dictionary")
 With ActiveSheet
 x = .Cells(1).CurrentRegion
 With oDic1
 For i = 1 To UBound(x, 1)
 If Not .exists(x(i, 2)) Then
 If Not oDic2.exists(x(i, 2) & " " & x(i, 3)) Then
 oDic2.Add x(i, 2) & " " & x(i, 3), Nothing
 .Add x(i, 2), 1
 End If
 ElseIf Not oDic2.exists(x(i, 2) & " " & x(i, 3)) Then
 oDic2.Add x(i, 2) & " " & x(i, 3), Nothing
 .Item(x(i, 2)) = .Item(x(i, 2)) + 1
 End If
 Next
 ReDim y(1 To .Count, 1 To 2): i = 0
 For Each e In .keys
 i = i + 1
 y(i, 1) = e: y(i, 2) = .Item(e)
 Next
 End With
 .Columns(5).Resize(, 2).Clear
 .[e1].Resize(UBound(y, 1), 2) = y
 End With
 End Sub

I wanted to count one value but this would be fine, thank you
