Play around with this script to see if it helps with what you are after
The script will identify which radio button is chosen
<script>
function resetAll(){ //checks to see if any radio buttons are selected
formfield=document.f1.rad // formname and input names to be checked
for(i=0;i<formfield.length;i++)
if (formfield[i].checked==true){ // if selected
formfield[i].checked=false // deselects
itext.innerText="Which one will you choose?" // the following 3 lines resets text back to original
itext.style.color=""
itext.style.fontWeight=""
}
}
function whichradio(){ // check for a selected radio button
formfield=document.f1.rad // formname and input names to be checked
for(i=0;i<formfield.length;i++)
if (formfield[i].checked==true){ // identify selected radio button
itext.innerText=("You have chosen radio button "+formfield[i].value) // show result
itext.style.color="black"
itext.style.fontWeight="bold"
}
}
