How to Recalulate Fields?

[Former Community Member]

How would you script the following:



An order form, with a calculated field - "TotalCost", to which you want to apply a surcharge percentage if a checkbox is checked. I can create it with a user entered field, but haven't been able to get it to work with a calculated field.



This is the script I have come up with to add 15% to a total (in the click event for the checkbox):



if (this.rawValue == "1")

TotalCost.rawValue *= 1.15;

else

TotalCost.rawValue /= 1.15;



Works fine for user-entered values, not at all for calculated data.
