Crosstab calculation

[ambatiuday]

Hi folks
I have a calculation in cross tab

My rows are Resource Type and nested with budget category
My columns are  Months(Jan,Feb,March-----)  and measure forecast

I need to calculate Month Over Growth  that  is
(Total of Feb- Total Of Jan)/Total of Jan) .This calculation should continue for the remaining months


Thank You
  Uday
