Excuse me if this has been posted before, I have tried finding a similar problem to no avail.
I have been setting up a Add Record form using the appropriate 'Insert Record Form Wizard'. All in all it's working, however, checkboxes are giving me grief.
I have set the values to 0,1. When the checkbox is not checked, the value inserted is NULL or empty, when checked, the value inserted is 0. Since I am building this application off an existing database, I am limited as to where I can be flexible for false values are already set to 0.
