<% Set upl = Server.CreateObject("SoftArtisans.FileUp") 

'--- Parse out the file name
FName = Mid(upl.UserFilename, InStrRev(upl.UserFilename, ) + 1)

'--- Retrieve the file's content type and assign it to a variable
FCONT = upl.ContentType

'--- Restrict the file types saved using a Select condition
Select Case LCase(FCONT)
