Just tested this... It works Mark... I think I was missing 'document'... Thanks for
the help and suggestions...
<HTML>
<BODY onLoad='initTable("table2");'>
<script language="javascript">
function getValue(optionName, hiddenValue) {
var s = document.frmTest.elements[optionName];
for (var i=0; i<s.options.length; i++) {
if (s.options[i].value == hiddenValue) {
s.options[i].selected = true;
break;
}
}
}
</script>
<form name="frmTest">
<input type="radio" onclick="getValue('abc','Mark')">
<br>
<select name="abc">
<option value="Joe">Joe</option>
<option value="Joseph">Joseph</option>
<option value="Jacob">Jacob</option>
<option value="Mark">Mark</option>
</select>
</form>
</BODY>
</HTML>

I was on the wrong lines anyhow..
forms[] and elements[] deal with the index and/or the names. options[]
requires the index.
the value is a property of the element not the option (at least i
recall things being like that.
I'd just pass the value of the element as an argument But my apologies
from not reading the question properly in the first place.
Cheers Mark
