a 'somewhat complex ' countif statement

[Dst3alth]

Hi, I want a way to do some analysis of a large data set , best way to explain is to show a little of the extract:

25.4 RPT_APPLICATION_D
25.4 RPT_APPLICATION_D
25.4 RPT_APPLICATION_D
25.5 RPT_ASSIGNED_AGENTS_D
25.5 RPT_ASSIGNED_AGENTS_D
25.6 RPT_CASH_ACCOUNT_D
25.6 RPT_CASH_ACCOUNT_D
25.6 RPT_CASH_ACCOUNT_D

Basically I want to be able to count the no of times in this example that 'RPT' appears in column B but ONLY when column A's Index no is unique i.e. I want the formula to return '3' rather than '8'

A quick way may be to have the data sorted, then use SUBTOTAL (on Data menu) - here's where you can use COUNT to count for you. It will insert a subtotal line with what you pick (sum, Count etc). Without SEEING your actual data, it is difficult to see what's in Column A and B. Peruse Subtotal on Excel and you should get what is desired.

a few options to return the conditional unique count, on XL2010 one would be:

=SUM(SIGN(FREQUENCY(IF(LEFT($B$1:$B$8,3)="RPT",MATCH($A$1:$A$8,$A$1:$A$8,0)),ROW($A$1:$A$8)-ROW($A$1)+1)))
confirmed with CTRL + SHIFT + ENTER
