I have a group of radio buttons named "LIST.VAR3_RADIO" that I need to clear when a dropdown list called "VAR29_1" is selected.

I assume it would be best to do this with javascript?

Any help would be appreciated.

Hi,

You can call this function;

function clearAllRadioButtons() {
var radList = document.getElementsByName('radioList');
for (var x = 0; x < radList.length; x++) {
if(radList[x].checked) radList[x].checked = false;
}
}
