Form Calculation using Radio Buttons ?

Question

I need to create a form to calculate the cost of an item after a discount is applied. However, the discount can be entered as either:

A flat dollar amount (price - discount = totalCost), or...
A percentage (discount/100 * price = totalCost)

I'm thinking the best way to do this would be to add two radio buttons next to the DISCOUNT input field;

Radio 1 would be for a flat dollar discount
Radio 2 would be for a percentage discount

And then the totalCost would use an IF/ELSE statement to calculate using the proper formula.

But I have no idea how to write that calculation. Can anyone help?

You can read about writing calculation scripts and "if" statements here:

To make this work we have to know the names of the fields involved and the export values of the radio buttons.

I'll just assume some names for the demo script, but you will need to modify it for the real names.

if(this.getField("DiscountType").value == "FlatAmount")
  event.value = this.getField("Price").value - this.getField("Discount").value;
else
  event.value = this.getFeld("Price).value * (1 - this.getField("Discount").value/100);

Correction: I just realized my percentage calculation should have been... price - (discount/100)price = totalCost Regardless, I need help writing the field script.
