Opinion Poll:<br>
what is your opinion regarding this HelpDesk Website:<br>
<br>
<input type=radio name=r1 value=g>Good
<input type=radio name=r1 value=a>Average
<input type=radio name=r1 value=b>Bad<br><br>
<input type=hidden name=a1>
<input type=hidden name=r1ans value=b>

if (fm.r1[0].checked || fm.r1[1].checked || fm.r1[2].checked)
{fm.r1ans.value = (fm.r1[0].checked) ? fm.r1[0].value : (fm.r1[1].checked) ? fm.r1[1].value : fm.r1[2].value;
fm.submit();}
