Conditional Checkbox yes to no - no to yes

[Pusher]

Hi all,
I have a problem with some checkboxes and conditions, I have a checkbox A and B – B is invisible and is automatically checked when A is checked (onclick event). I want this to be the case when A is 0 to 1 but not the case when it’s already checked and goes from 1 to 0. This happens on form - on current event when A is set to 1 without the onclick event so it can be changed to 0 if need to. In this case when A is automatically set to 1 and then changed to 0 I need B not to be changed to 1. How do I do this?

Have you tried;

If Me.CheckA = True Then Me.CheckB = True

This could be in the Click event or the After Update event
