本人菜鸟，刚接触Asp，现在做一个文章管理后台。
为了实现一个复选框与下拉菜单动态关联的功能：
也就是勾选复选框的同时，显示下拉菜单。不选时，下拉菜单不显示。
问题如下：

//
错误类型：
Microsoft VBScript 运行时错误 (0x800A000D)
类型不匹配: '[string: "2, 11, 18, 24, 32, 3"]'
//
以下是我代码：   

            <%            
Dim SearchString, SearchChar, MyPos ,strtoSite
SearchString ="cautism,hnspe,cyyza,cxxkn,kdnlxl,guduzheng"
SearchChar   = request("toSite")
MyPos = Instr(SearchString, SearchChar)


      

%>

               <input name="toSite" type="checkbox" id="toSite" value="cautism"<% if Mypos >0 then Response.Write (" checked")%>>
             cautism  
            
             <select name="toClassID" size="1" >
             <%If isEdit Then%>
              <option value="0"<%If Rs("toClassID") = 0 Then Response.Write (" selected")%>>请选择版块</option>
              <option value="1"<%If Rs("toClassID") = 1 Then Response.Write (" selected")%>>新闻1</option>
              <option value="2"<%If Rs("toClassID") = 2 Then Response.Write (" selected")%>>新闻2</option>
