Code:
function unselect()
{
  document.forms[0].dutyid.checked = false;
}
should do it. Hoever if you have more than one radio button with the same name you will need to refer to them specifically, I would use:
Code:
var oRadio = document.getElementsByName("dutyid")[0]; //replace 0 with index of button if necessary
oRadio.checked = false;
Normally if you only have one button then it should be a checkbox.
