aspsmartupload filnavn

jeg har denne kode.. og den virker fint nok.. skal bare have lavet så man kan rette filnavnet til noget jeg bestemmer fx. Session("idnummer")

  <%
mode = request.QueryString("mode")
if mode = "" then%>
<form action="?mode=up" method="post" enctype="multipart/form-data">
<input type="file" size=40 name="File1"><br>
<input type="submit" value="Upload">
</form>
<%
elseif mode = "up" then

Dim objUpload

Set objUpload = Server.CreateObject("aspSmartUpload.SmartUpload")

objUpload.MaxFileSize = 500000

On Error Resume Next

Dim strUploadPath

strUploadPath = "/upload/"

Dim intFileCount

objUpload.Upload

intFileCount = objUpload.Save(Server.MapPath(strUploadPath))

If Err Then
Response.Write "Der opstod en fejl :<br>" & vbCrLf
Response.Write Err.Description
Else
Response.Write intFileCount & " fil(er) uploadet.<br>" & vbCrLf
End If

On Error Goto 0

Set objUpload = Nothing

end if
%>
