I'm making an order form and need some help using JavaScript to set the values of some of the tags in the HTML FORM.

In the order FORM there will be a hidden tag for the price (example: <type=HIDDEN name=PRICE value=123>). For each item there will be a set of radio buttons for certain options. The options are mutually exclusive so radio buttons are used instead of check boxes (i.e. only one option per item).

Here's what I need:

Depending on which radio button is CHECKED the value of the PRICE tag in the FORM needs to be changed. IOW, if the customer CHECKS radio button 1 PRICE=whatever1, for radio button 2 PRICE=whatever2, etc etc.

Any help is appreciated - Thanks!
