Radio button issue with Javascript

[spanky1339]

I'm trying to create a select all functionality with a radio button. Basically selecting one radio button would automatically select a number of other radio buttons in the form. I figured I could loop through all the radio buttons on the form and then call the values of the ones I needed to check. This doesn't seem to work. Any ideas?

function checkEmail()
{
with (document.choice) {
for (var i=0; i < elements.length; i++) {
if (elements[i].type == "radio'")
if (elements[i].value == "email2" && elements[i].value == "email3")
elements[i].checked = true;
}
}
}

I would call this function with an onClick in my slect all radio button. I want it to check the other radio buttons in the form with values "email2" and "email3"
