I work in a law firm and am attempting to create a document which calculates formulas.

This is what I need:

I have a paragraph based on IF/THEN - If there is child support involved, then we need to subtract that number from a number above. The number above is

{ =((settlefee)-(costs)-(settlefee*25%)) \# "$#,##0.00;($#,##0.00)" \*DollarText \*Upper }

This formula works. I want to be able to bookmark the formula result and put it in my IF/THEN paragraph with another formula. That formula would be the result above less the child support. So, I want something to the tune of { =resultabove-support }.

Is there a way to do this?
