Question

Consider:

 Cells(2, "Q").Formula = "=COUNTIF(P$1:P1,P2)=0"

How do I insert these formulae when I have a variable holding a value?

I have to start the formula at 3550 row and 4000 row somtimes. It depends on the data. Well, when I googled it, I found nothing. They all used the same formula, but I need to insert the countif function at a particular cell, may be at 300 or 500 – it depends in the variable value.

 Cells(count,"Q").formula = "=COUNTIF(cells($1,"P"):cells(count-1,"P"),cells(count,"P))=0"

Is this the way? Well, I tried in some ways but it’s ending up higlighting the line with the red colour. How do I insert these formulae with a variable?

Answer 1

Try this:

'case 1: if you know the destination range
Range("Q2").Formula = "=COUNTIF(P$1:P1,P2)=0"
Range("Q2").Copy Destination:=range("Q3:Q500")

'case 2: if the destination range is a variable
'minRow is a Long >= 1
Range("Q" & minRow + 1).Formula = "=COUNTIF(P$" & minRow & ":P" & minRow & ",P" & minRow + 1 & ")=0"
Range("Q" & minRow + 1).Copy Destination:=Range("Q" & minRow + 1 & ":Q" & maxRow)
