Operation is not allowed

Jeg får fejlmeddelelsen:

Operation is not allowed when the object is closed.
/workstatistics/index.asp, line 521

Linje 521 er der hvor jeg bruger update metoden, her er min kode:

If Request("WhatWasChosen") = "DeleteData" Then
  Set objConn = Server.Createobject("ADODB.Connection")
  strConnString = "Provider=SQLOLEDB;" & _
                  "Persist Security Info=FALSE;" & _
                  "User ID=sa;" & _
                  "Password=pb16950;" & _
                  "Initial Catalog=WorkStatistics;" & _
                  "Initial File Name = C:\Programmer\Microsoft SQL Server\MSSQL\" & _
                  "DATA\WorkStatistics_Data.mdf;"
  objConn.Open strConnString
  intPrimaryKey = Request.Form("PrimaryKey")
  strSQL = "DELETE FROM WorkProjects_T WHERE Primary_Key_BI = '" & intPrimaryKey & "'"
      Set objRS = Server.Createobject("ADODB.Recordset")
      objRS.Open strSQL, objConn, adOpenDynamic, adLockPessimistic, adCmdText
      objRS.Update
      objRS.close
      Set objRS = Nothing
      objConn.close
      Set objConn = Nothing
  Response.Write "<B>Postsættet med primær nøglen " & intPrimaryKey & " blev slettet.</B>"
End If

Hvad er der galt?
P.s. Den sletter postsættet alligevel!
