Form submitting to 2 actions depending on radio button selct

Hi,
I am working in php(wordpress). I am ok, but not brilliant at it. So I have a form with some fields, 3 radio buttons and one submit button. The main action will be submitting to wordpress db. The second action will be submitting to a url depending on which radio button is selected.
Example:
Select Choice A and hit submit. The form will go to wordpress db and choice a’s url. Select Choice B and hit submit. The form will go to wordpress db and choice b’s url.

I am finding out this is easier said than done. I have spent way too long trying to figure this out. I am hoping it is just my inexperience with php!

I found a js script that changes the action depending on which radio button is selected. It works great, but it only sends to one action. I need it to send to 2 actions.

Any suggestions, thoughts, would be greatly appreciated.

Thanks
Will
