Percentages in Grouping Header

[Wei]

Hi,

I am trying to put a count as well as a ratio in my group header.  The ratio has a simple formula (Current Group Count / Previous Group Count).  Has anyone done this?

World  Count:7,000,000,000 Percentage: 100%
Canada Count: 35,000,000 Percentage 0.05%
        Alberta Count 3,000,000 Percentage 0.85%
              Calgary Count 1,000,000 Percentage 33%

Thanks for your help
