The simple way to achieve what you asked about is to create a query based on your table, create a calculated field that converts the Yes/No to 1/0 and use that as the basis for your form:
SEC: Iif([answer], 1,0)
But why? Why 1/0 instead of a checkbox? What's the big picture--how is this form to be used, what does 1/0 allow you to achieve?
Also, that assumes [answer] is a yes/no field. Is that its data type? Or is it a text field where you literally have "yes" and "no" values?
