麻烦解决一下这个问题

看一下以下的代码，为什么改为自动时，组号还是disabled?是什么问题啊？
<form name="AdapterForm1" method="post">
<select name="AdTCall" class="inputgreen" language=javascript onChange="return AdTCall_onchange()"><option value="0" selected>手动</option><option value="1">自动</option>
</select></td><td width="80" >组号</td><td width="159" > <select name="AdGroupNo" disabled><option value="1" selected>1</option><option value="2">2</option><option value="3">3</option></select>
</form>
<SCRIPT ID=clientEventHandlersJS LANGUAGE=javascript>
<!--
//错误提示
function AdTCall_onchange()
{
switch (AdapterForm1.AdTCall.Value)
{
case "0":
AdapterForm1.AdGroupNo.disabled=true;
break;
case "1":
AdapterForm1.AdGroupNo.disabled=false;
break;
}
}
// -->
</script>

将switch该为
switch (document.AdapterForm1.AdTCall.options[document.AdapterForm1.AdTCall.selectedIndex].value)

测试通过
