Try this out ...


if(textField11 != null )
{
alert(" 4 "+textField11);
document.EnableDisable.TextField11.disabled = false;
document.EnableDisable.TextField12.value ="";
document.EnableDisable.TextField13.value = "";
document.EnableDisable.TextField12.disabled = true;
document.EnableDisable.TextField13.disabled = true;

}

and while checking for null also check for ""

You probably want to look at the lenght property instead of null.
