Calculating the %?

[robowen]

Hi all,

%given can be any number depending on customer's discount. So then how do I calculate the varible% of the subtotal in the total% field?

Thanks You!

field1-----field2-----subtotal-----%given---total%

-£25--------£75---------£100--------50%------£50

-£50--------£50---------£100--------25%------£25
