UPDATE EXISTING RECORD IN MS ACESS USING ASPUPLOAD

I'm using ASPUpload to upload a file and add the filename to the db. i need to do this while UPDATING existing ms access db records.  I've taken this code into the stratusphere somehow and I'm not sure where I'm going wrong.  The form variable I'm tryiing to pass is ContentID. Basically I'm looking for this:

add filename to  db record where ContentID=FormParam.ContentID - here's my code:

<%
      Set Upload = Server.CreateObject("Persits.Upload")

      ' Capture files
      Upload.Save "E:\inetpub\wwwroot\smbb\newsite\news\pdfs\"

      ' Obtain file object
      Set File = Upload.Files("THEFILE")

      For Each File in Upload.Files

            datapath="E:\inetpub\wwwroot\smbb\smbb.mdb"
            strConn="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & datapath
            Set objConn = Server.CreateObject("ADODB.Connection")
            objConn.Open strConn  
            







 

      
            set rs = Server.CreateObject("ADODB.RecordSet")
      
Dim rsContentID__MMColParam
rsContentID__MMColParam = "ContentID"
rsContentID.Source = "SELECT * FROM Content WHERE ContentID = " + Replace(rsContentID__MMColParam, "'", "''") + "" 
            
            rs.Open "Content",objConn,1,2
            if len(EditRecordFlag) = 0 then
  rs.AddNew
end if
            rs("filename") = File.ExtractFileName
            rs.Update
            rs.Close
            set rs = nothing
            objConn.Close
            set objConn = nothing

            Response.Write "Your PDF has been successfully uploadedd.  <a href='index.asp'>Click here</a> to return to the admin."
      Next
%>

thanks!
