complicated formula

[iangel79]

hi, all,

I have a sheet with the following content

total 12 (sum Group1+group 2)

Group 1 3(sum product a+product b)
Product a 1
Product B 2

Group 2 9(sum product c+product d+product e)
product c 2
product d 3
product e 4

Is thehe a formula which calculates automaticly the sha re of al
products from there group and the share of all groups from the total.

Thank you!
I
