Hjælp til regel: IF "ikke eksisterer" then msgbox"bla bla" exit

Nu starter vi helt forfra.... Point værdi er steget til 100 som går til den der kan give mig en komplet løsning.

Håber i kan hjælpe mig. Hvis i mangler flere info så sig til.

Vigtigt:
MyEmailAddress er en forespørgsel over tabelen dbo_VEHICLE som har Feltet REGISTER_NUMBER som her skal søges på.


Skal bruge en "IF "regnr ikke eksistere i"...Then...msgbox"mangler bla bla"...exit function, Else" kode i 2 punkter af min kode.

Første sted (har forsøgt med hjælp herfra men virker ikke):
-------------------------------------------------------------------
  Regnr = InputBox("Indtast kundens registerings nummer")

If DCount(dbo_VEHICLE.REGISTER_NUMBER, MyEmailAdresses, "REGISTER_NUMBER Like '" & UCase(Regnr) & "'") = 0 Then

MsgBox "Registreringsnummer ikke fundet"
Exit Function

Else
------------------------------------------------------------------


Det andet sted (hvor "LAST_SERVICE_TXT" skal være større end nul):
-----------------------------------------------------------
Set MyMail = MyOutlook.CreateItem(olMailItem)
     
     
     
         
            ' This addresses it
            MyMail.To = MailList("LAST_SERVICE_TXT")
----------------------------------------------------------










Den komplete kode:
-------------------------------------------------------------


Option Compare Database
Option Explicit
' You need to declare a reference to the Outlook library, and the filesystemobject.
' this is not as hard as it sounds.
'
' Look in the menu above, and click Tools, then select References
'
' Scroll down the list until you see
' Microsoft Scripting Runtime -- and put a check next to it (if one is not there already)
'
' Microsoft Outlook Object Library -- check that.
'          There will be some version number there as well; it doesn't matter.
'          This will work with Outlook98 and Outlook2000 and OutlookXP.  It hasn't been tested on Outlook 2003 yet.
