You have to loop over the radio buttons and check which one is checked, e.g.
[CODE=javascript]var browsers = document.getEle mentsByName("tx t_browser");
for (i = 0; i < browsers.length ; i++) {
if (browsers[i].checked) // you've got it here...
}[/CODE] Your code is trying to use a mixed-up version of something that would work for select drop down elements.
