Auto fill values when checkbox selected

[HickoryII]

I’m a beginner at Access and would like to know: Is there a way to automatically fill in specific values in a table or datasheet form when a form checkbox is selected?

Yes, check out the Before Update (or potentially the After Update) event of the checkbox.

VBA would be the best.
But what do you do if they check it, then think, OOPS, and uncheck it again?
