基础问题，帮我把这几行c#改成asp的 （vbscript）

麻烦兄弟们了。。帮我把这段C#代码， 翻译成asp的 vbscript的

C# code:

if (paths != "")
{
if (videoType == "music" || videoType == "")
{
try
{
if (System.IO.Directory.Exists(Server.MapPath("/upfile/sound/" + paths + "/")))
{
this.plSound.Visible = true;
}
}
catch
{ }
}
if (videoType == "video")
{
plVideo.Visible = true;
}
}

---

我是这么写的，不过貌似会出错。。。
主要是中间那个if Server.MapPath 不会判断

VBScript code:
if paths != "" then
if videoType == "music" || videoType == "" then

if Server.MapPath("/upfile/sound/" + paths + "/")！="" then
this.plSound.Visible = true
