I want to copy a formula down a column but the cell reference needs to be
changing by more than one. ie. my formula in A1 is =B1, my formula in A2 is =
B11. So when I now copy the formula in Column A down I want my formula in A3
to = B21 but when I highlight A1 and A2 then drag down my formula in A3 is
=B3. Any help much appreciated.
