justsomeguy 1,135 Posted May 1, 2012 Report Share Posted May 1, 2012 You'll need to use a function to do that instead of having all of the code inline. If the function sees an operator then it will need to store the current values in variables before it resets the field so that it can get that value later to do the calculation.
