Sql problemer!!

Så er jeg her igen kan ikke faa dette til at virke,
Jeg ved at det er en basal ting jeg har lavet forkert men her kommer lige fejlen og noget kille kode.

Fejlen:
Microsoft OLE DB Provider for ODBC Drivers fejl \'80040e07\'

[Microsoft][ODBC Microsoft Access-driver] Datatyperne stemmer ikke overens i kriterieudtrykket.

/brugere_rediger_send.asp, linje 22

her kommer bruger_rediger_send.asp
