what does it mean by this?

Error Type:
Microsoft OLE DB Provider for ODBC Drivers (0x80004005)
[Microsoft][ODBC Microsoft Access Driver] Operation must use an updateable query.
/kiosk/kiosk1.asp, line 115

either your not closing your DB Connections and its leaving it locked.
or
you may not have write access on the Database, Check that your iusr_computer has write access both to the directory of the DB and to the DB itself.

Hope that helps.

Post your code for the connection and execution.
