Fejl i script!

Jeg prøver her at copy/paste hele min kildefil...

Jeg får følgende fejlmeddelse når jeg vil bruge at skrive brugernavn og adgangskode!

Error Type:
Microsoft JET Database Engine (0x80004005)
Microsoft Jet-databasemotoren kan ikke åbne filen "c:\Inetpub\wwwroot\butik\db\butik.mdb". Den er allerede åbnet med udelt adgang af en anden bruger, eller du skal have tilladelse til at vise dataene.
/butik/login.asp, line 14
