expression field recalculating

[mgraye]

i am designing a from to pull values from a database and populate numerous
drop down boxes. then i add an expression field to multiply one of the
values in one drop down box by the value in another drop down box. it works
when a value is first selected, but then does not change if another value is
selected. what is the setting for the expression to change everytime the
selected value changes?

Create a rule on both drop-down list boxes that will do the calculation and
set the value of the expression field.
