asp图片上传，请帮我看看下面的代码哪里错误？

<!--#include FILE="upload_5xsoft.inc"-->
<%
set upload=new upload_5xsoft
set file=upload.file("file1")
if file.fileSize>0 then
filename=fupname+"."
filenameend=file.filename
filenameend=split(filenameend,".")
n=UBound(filenameend)
filename=filename&filenameend(n)

if fuptype="adv" then
savepath="../images/adv/"&filename
elseif fuptype="pic" then
savepath="../pic/digi/"&filename
elseif fuptype="pic1" then
savepath="../pic/digi1/"&filename
elseif fuptype="link" then
savepath="../images/links/"&filename
elseif fuptype="db" then
savepath="./"&filename
end if
file.saveAs Server.mappath(savepath)
response.write "文件上传成功!上传文件的物理路径为："
response.write "<font color=red>"&Server.mappath(savepath)&"</font><br><br>"
response.write "<a href='"&savepath&"'  target='_blank'>点击预览上传的文件</a>"
response.write "<br><br><INPUT onclick='javascript:window.close();' type=submit value='上传完成'>"
%>

这段代码运行之后提示哪一行有错误？
