asp switch嵌套语句该怎么写啊？
现在有一个保险表单提交的页面，http://www.5iucn.com/insurance.html，后台我能得到客户端选择的保险类型和起止日期的差值并且能写入到数据库，现在的问题是，我如何才能用switch语句把类型和起止日期关联起来确定最终的钱数，后台代码如下：<%
set cn=server.CreateObject("ADODB.Connection")
set rs=server.CreateObject("ADODB.Recordset")
set rs2=server.CreateObject("ADODB.Recordset")
cn.Open mycnstr
visaid=Request.QueryString("visa")
if Request.ServerVariables("REQUEST_METHOD")="POST" then
sqltext="select * from safeorder"
rs.Open sqltext,cn,1,2
rs.AddNew
rs("id")=getkeyid("safeorder","id")
rs("orderno")=newformatdate(Cstr(now()))
rs("name")=Request("name")
rs("enname")=Request("enname")
rs("sex")=Request("sex")
'rs("userid")=Request("user")
rs("sex")=Request("sex")
rs("passport")=Request("passport")
rs("birthday")=Request("birthday")
rs("destination")=Request("destination")
rs("duration")=Request("duration")
rs("type")=Request("type")
rs("date")=Request("start_date") '得到客户端输入的开始日期并写入数据库
rs("date1")=Request("end_date") '得到客户端输入的结束日期并写入数据库
d1=request.Form("start_date")
d2=request.Form("end_date")
d3=DateDiff("d",d1,d2)
rs("date2")=d3
rs("company")=Request("company")
rs("phone")=Request("phone")
rs("email")=Request("email")
rs("address")=Request("address")
rs("description")=Request("description")
rs("status")=0
rs("flag")=1
rs("creatdate")=now()
rs("editdate")=now()
rs.Update
rs.Close
If Request.Cookies("userid") = "" Then
reurl="insurance.html"
response.write "<script language=javascript>alert('订单提交成功,稍后工作人员将与您联系！');window.location.href='"+reurl+"';</script>"
else
response.write "<script language=javascript>alert('订单提交成功,稍后工作人员将与您联系！');window.location.href='usercenter.asp?mode=2';</script>"
end if
end if
%>
[解决办法]
select case xxx case xxx ... case xxx ... case xxx select case yyy case yyy ... ... end select case else ...end select
