Problem with Radio Button error "[object HTMLInputElement]"

Sep 5th, 2008

Hello,

I am having problems retrieving correct values from two radio buttons in my AJAX script below.

The radio button values are either a 1 or 0 and always produces 0 regardless of which button is selected.

Once in AJAX, I can not have the script retreive a 1 or 0. AJAX script produces "[object HTMLInputElement]" as the response. Not sure what is going wrong.

Thanks in Advance.
Diego

Aren't you using the wrong variable in your AJAX URL string?

You assign the "search17" element to the "proc17" variable and then use that in your URL.
Shouldn't the "search17" variable be in the URL?
