Copy and paste formula outside pivot table using information from table

Hi all,


I have a pivot table with lots of information on it, and I am wanting to add a formula outside the pivot table that divides one cell by another from within the pivot. At the minute it will let me do the first one but then when I try and copy and paste the formula down, the same information from the original formula shows. Is there a way of copy and pasting the formula so that it changes information? I have attached the pivot table to show you what I am looking for. Eventually there will be many of these pivots so will be a long task manually setting up the formulas to divide the two cells.

Thanks for looking,
Gemma
