Problem med dato

Jeg har stirret mig blind på denne kode, er der nogen der kan hjælpe mig med at få rettet den. Jeg tror den er gal med datoen.

Set Conn = Server.CreateObject("ADODB.Connection")
DSN = "DRIVER={Microsoft Access Driver (*.mdb)}; "
DSN = DSN & "DBQ=c:\www\fmpartner.dk\dynamicinn\db\database.mdb"
Conn.Open DSN

strSQL = "Insert into shop_orders ("

strSQL = strSQL & "kundeid, "
strSQL = strSQL & "ordrer, "
strSQL = strSQL & "levering, "
strSQL = strSQL & "leveringsdato, "
strSQL = strSQL & "notat, "
strSQL = strSQL & "betaling, "
strSQL = strSQL & "dato, "
strSQL = strSQL & "godkendt) "

strSQL = strSQL & "values( "

strSQL = strSQL & "'" & Session("kundeid") & "', "
strSQL = strSQL & "'" & Teksten & "', "
strSQL = strSQL & "'" & Request.Form("levering") & "', "
strSQL = strSQL & "'" & Request.Form("leveringsdato") & "', "
strSQL = strSQL & "'" & Request.Form("notat") & "', "
strSQL = strSQL & "'" & Request.Form("betaling") & "', "
strSQL = strSQL & "'" & Request.Form("dato") & "', "
strSQL = strSQL & "'Ja')"

Conn.Execute(strSQL)
Conn.Close
Set Conn = Nothing

Fejlen hedder:
Microsoft OLE DB Provider for ODBC Drivers error '80040e07'

[Microsoft][ODBC Microsoft Access Driver] Data type mismatch in criteria expression.

/confirm.inc, line 83

Linje 83 er: "Conn.Execute(strSQL)"
