code makes all fields empty when one field is left blanc

[JeroenMioch]

Dear fellow programmers,

Can anyone tell me why the code listed below makes the fields in my table (and thus in my continous form) go empty ?
If i fill in all the controls it works perfectly. But when i leave one control empty then all the fields will be empty :

See the screenshot below, if i hit the button "Opslaan"(wich means SAVE) then the data will not transfer from the line with the white background (these are not bound fields) to the records with the light grey bachground (continous form).

Dim db As DAO.Database
Dim rs As DAO.Recordset
Dim strSQL As String
    Set db = CurrentDb
    Set rs = db.OpenRecordset("tblSluitSystemen", dbOpenDynaset)
    rs.AddNew
        rs!Soort = Me.ctrlSoort
        rs!Merk = Me.ctrlMerk
        rs!LengteBinnen = Me.ctrlLengteBinnen
        rs!LengteBuiten = Me.ctrlLengteBuiten
        rs!KnopCilinder = Me.ctrlKnopCilinder
        rs!KnopZijde = Me.ctrlKnopZijde
        rs!SerieNummer = Me.ctrlSerieNummer
        rs!Sluitsysteem = Me.ctrlSluitsysteem
        rs!UitgevenAan = Me.ctrlUitgevenAan
        rs!DatumUitgegeven = Me.ctrlDatumUitgegeven
        rs!KostenPlaats = Me.ctrlKostenPlaats
        rs!SoortObject = Me.ctrlSoortObject
        rs!Object = Me.ctrlObject
        rs!Bouwdeel = Me.ctrlBouwdeel
        rs!Etage = Me.ctrlEtage
        rs!KamerNummer = Me.ctrlKamerNummer
        rs!Historie = Me.ctrlHistorie


    rs.Update
      
 
        Me.ctrlSoort = Null
        Me.ctrlMerk = Null
        Me.ctrlLengteBinnen = Null
        Me.ctrlLengteBuiten = Null
        Me.ctrlKnopCilinder = Null
        Me.ctrlKnopZijde = Null
        Me.ctrlSerieNummer = Null
        Me.ctrlSluitsysteem = Null
        Me.ctrlUitgevenAan = Null
        Me.ctrlDatumUitgegeven = Null
        Me.ctrlKostenPlaats = Null
        Me.ctrlSoortObject = Null
        Me.ctrlObject = Null
        Me.ctrlBouwdeel = Null
        Me.ctrlEtage = Null
        Me.ctrlKamerNummer = Null
        Me.ctrlHistorie = Null

Any help would be greatly appreciated.
