ASP网页后台无法上传

下载了一个破解版的ASP源码，现在后台在down.asp(下载)里无法上传图片及文件。在news.asp里确可以上传图片。以下是upload.asp的编码，请高手帮着看看哪里出问题了，谢谢！
'============================================================下载图片
sub downpic()
if Request.QueryString("submit")="downpic" then
uploadpath="/uploadFile/softdown/downpic/"
uploadsize="102400"
uploadtype="jpg/gif/png/bmp"
Set Uprequest=new UpLoadClass
    Uprequest.SavePath=uploadpath
    Uprequest.MaxSize=uploadsize*102400
    Uprequest.FileType=uploadtype
    AutoSave=true
    Uprequest.open
  if Uprequest.form("file_Err")<>0  then
  select case Uprequest.form("file_Err")
  case 1:str="<div style=""padding- :5px;""> <font color=blue>上传不成功!文件超过"&uploadsize&"k [<a href='j (-1)'>重新上传</a>]</font></div>"
  case 2:str="<div style=""padding- :5px;""> <font color=blue>上传不成功!文件格式不对 [<a href='j (-1)']>重新上传</a>]</font></div>"
  case 3:str="<div style=""padding- :5px;""> <font color=blue>上传不成功!文件太大且格式不对 [<a href='j (-1)'>重新上传</a>]</font></div>"
  end select
  response.write str
  else
  response.write "<script language=""javascript"">parent.form1.showpic.value='"&Uprequest.SavePath&Uprequest.Form("file")&"';" 
  response.write "</script>"
  response.write "<div style=""padding- :5px;""> <font color=red>文件上传成功</font> [<a href='j (-1)'>重新上传</a>]</div>"
  end if
Set Uprequest=nothing
end if
response.write "<form name=form action=?action=downpic&submit=downpic method=post enctype=multipart/form-data>"
response.write "<input type=file name=file class='tx' size='20'> "
response.write "<input type=submit name=submit value=上传 class=""tx1"">"
response.write "</form>"
end sub

全部
