Thanksfor helping.

Answer 1

If the radiobuttons are within a form, then I am certain you can replace the lines marked
<input type="radio" name="radiobutton" value="proID" > and
<input type="radio" name="radiobutton" value="proDesc" >
with
<input type="radio" name="radiobutton" value="proID" onClick="return onClickRadioBtn(this)">
and
<input type="radio" name="radiobutton" value="proDesc" onClick="return onClickRadioBtn(this)">
respectively.
You will then need to create the following JavaScript functions:
<script language="JavaScript">
function onClickRadioBtn(oRadioBtn)
if(oRadioBtn.value == "proID")
//Perform desired steps for ProID radio button
else if (oRadioBtn.value == "proDesc")
//Perform desired steps for ProDesc radio button
else
//Perform desired steps for a function call having
// neither values of the proID nor proDesc
return true;
</script>
Again, I am sure this solution works for objects within a <form name="xyz"...> html form. There is a possibility that this function call will work outside of a html form environment, but I simply can't recall implementing it in that fashion.
Hope this helps.
