[求助]使用无组件文件上传时出错!

使用无组件文件上传时出错:

Microsoft VBScript 编译器错误 错误 '800a03f6'

缺少 'End'

/iisHelp/common/500-100.asp，行242

服务器对象 错误 'ASP 0178 : 80070005'

Server.CreateObject 访问错误

/schoolmate/include/upclass.asp，行40

检查权限时Server.CreateObject 的调用失败。对此对象的访问被拒。
第40行的代码是:
Set objData = Server.CreateObject("Scripting.Dictionary")
问题出现在 Scripting.Dictionary 上面,空间好像不支持Scripting.Dictionary
放到别的空间或本机可正常使用.

请教怎样才能让服务器支持这个功能呢？
