Syntax error i SQL

Nedenstående kode giverflg. fejl:

Microsoft OLE DB Provider for ODBC Drivers error '80040e14'
[Microsoft][ODBC Microsoft Access Driver] Syntax error (missing operator) in query expression ''Hans' Familyname = 'Larsen' Function = 'CEO' Department = 'IT' Country = 'DK' Mobilephone = '+45 8899' Email = 'cra@mail.dk' Registrationdate = '05-10-2007 12:44:38''.

Som det kan ses på udskrivningen af SQL'en mangler der nogle data. Hvem kan hjælpe med at finde fejlen?
