tblStatus should not have a KlantID
In tblKlant the StatusID should be numeric not short text
I would call Status in tblKlant StatusID_FK
You now have two fields called Status in two tables with different meaning. In the Status table Status is the description. In the Klant table Status is the ID. Very confusing.
My naming Convention Always.
StatusID
StatusDescription
in the foreign table
StatusID_FK
