I have the following line of code that works for a critera set in sheet Target cell A" and returns in sheet Target cell B2 the correct answer, however when it moves down a row it still refers to A2 not A3can anyone advise me how to progress the A2 to become A3 and so onI have tried storing an intiger in a variable R and changing the code to 
=Target!A" & R
, but i get an errorCells(R, 2).Formula = 
 "=SUMPRODUCT((Data!A2:A" & DataLastRow & " =Target!A2)*Data!B2:B" & DataLastRow & ")"
