This UDF will look in the first column in a Table or Range for the N'th occurrence of a specified value, then look in a nominated column for another specified value on the same row. It will then return the result from the same row in a specified column.

The Code:

Function FindNth(Table As Range, Val1 As Variant,Val1Occrnce As Integer, _

                  		Val2 As Variant,Val2Col As Integer, ResultCol As Integer)

	Dim i As Integer

	Dim iCount As Integer

	Dim rCol As Range



		For i = 1 To Table.Rows.Count

			If Table.Cells(i, 1) = Val1 And _
				Table.Cells(i, Val2Col) = Val2 Then

				iCount = iCount + 1

			End If



			If iCount = Val1Occrnce Then

				FindNth = Table.Cells(i, ResultCol)

				Exit For

			End If

		Next i

End Function

Formula	=FindNth(A1:E12,"Dog",2,"Male",3,5)
Result	15/06/99

The Table range is A1:E12
"Dog" is the value to find in the first column of A1:E12
2 is the occurrence of "Dog" to find in the first Column of A1:E12
"Male" is second value to find
3 is the relative position of the column in A1:E12 to find "Male"
5 is the relative position in the column to return our result from

In other words, find the second occurrence of a Male Dog and return the result from the same row in the fifth column. It is important that the code is case sensitive. This can be overcome by using:
