Radio Buttons Sub Total Script

[stretcher012599]

I have a form that has 10 radio buttons, each radio button represents a product. For each product, there is a different dollar value assocciated with each product. The form also has 3 text boxes, sub total, discount and total. The user will select 3 products from the list, and the product that is the lowest price will be the discount. Example: I check 3 products on the list, product 1 is $3.00 product 5 is $7.50 and proct 9 is $1.50 The sub total will be $12.00 and the discount will be $1.50 and the total will be $10.50

Can someone please show me an example on how I can do this without pressing the submit button. Thanks

You could use the onchange event... either add it manually onto each form element that could/should trigger your calculation code to update the form, or do it using javascript (maybe triggered on a class or something).

Either way, you trigger it run a function:

...
<input type="text" name="qty1" value="" [!]onchange="refreshForm()"[/!]/>
...
<input type="radio" name="opt1" value="Y" [!]onchange="refreshForm()"[/!]/>
...

You get the idea

Cheers,
Jeff
