在vbs 中怎么才能引用select
中某一项被选中的项的值

<%@LANGUAGE="VBSCRIPT" CODEPAGE="936"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">

</head>

<body>
<SELECT ID="oSelect" NAME="Cars" size="5" >
<OPTION VALUE="宝马" SELECTED>宝马</OPTION>
<OPTION VALUE="保时捷">保时捷</OPTION>
<OPTION VALUE="奔驰">奔驰</OPTION>
</SELECT>
<input name="but3" type="button">
<script language="VBScript">
sub but3_onclick
set oOption = document.createElement("OPTION")
oSelect.options.add(oOption)
oOption.innerText = "Two"
oOption.value = "2"
end sub


sub oSelect_onchange
dim mystr
mystr=oselect.optios[oselect.selectedIndex].value
window.alert mystr
end sub


</script>

</body>
</html>

出错在哪里啊

[是是非非]

mystr=oselect.optios[oselect.selectedIndex].value

==>

mystr=oselect.options(oselect.selectedIndex).value


1、optios 改成 options 拼写错误
2、VBS里面取数组是用()不是[]
