You need something like the following code.

Dim strSQL As String
 
   strSQL = "UPDATE Room Set Register = True WHERE RoomID=" & Me!RoomID
   DoCmd.RunSQL strSQL

Thanks for the reply. Where can I put those code. Is it in the save button or After Update event? And with the code, did I need to add the checkbox in the form?
