I have created a table that contains 'UserName', 'Password', and 'Level'. I created a form with two text boxes. One is for the username, and one is for the password. The form also has two command buttons. One is to 'Log In', the other is to 'Quit'. What code do I need to put in the On Click section of the Log In button to validate that the UserName and Password are correct? How do I save the UserName to a variable so that I can use it again later?
