that was goodbut
running what?
how can i find out if a radio button has been checked or not
in the input put onClick="itwaschecked(this)"
or something
function itwaschecked(obj) {
// whatever to the event it was clicked
}
then run whtever you want on that event
btw: window and document are their own objects
window.document is wrong
either
window.
or
document.
you can't try and access two elements
elements[0][0].checked
that's why the error comes up

running = see if it works properly in your browser
btw window.document does work.
So how can i see if the radio button is checked?
here's an example:
var path = window.document.myform
for (i=0;i<path.elements.length;i++)
{
if (path.elements[0].checked == true)
{alert('YEEAAAAHHAAAA'))
}
Asuming all form elements are radios...
But still this will return an error.

I'll stick with the window thing but

What if there are moer radio buttons under the same name, how do you divide them?
I mean:
<input type="radio" name="k">
<input type="radio" name="k">
<input type="radio" name="k">
So what if i want to check if any radio button under the same group was checked?
Well i just figured it out.
i just do:
window.document.forms[0].elements[0,0].checked
instead of:
window.document.forms[0].elements[0][0].checked
Thanks for all the help.

remember the incrementing of the counter in a loop will take a bit more logic to test for a group of radios or checkboxs (same thign basically) _______________________________________________

on the window document object referencing
it really isn't needed to add window.document
document is a child object of the window object but not normally referenced as such. I believe the need for that ws taken away in like NN 1 _______________________________________________
