Option Button with Negated Value

[rohnds]

I have an option button on my main form. You click on the option button to display all the cars available. But in my table the available cars are stored "False".
Is there anyway, I can change the values of the option button such that they work the opposite.
For example, if I click on the option button, I want the value False instead of True and vice versa.

Am I to understand that you have bound yout Option Button to the Available field in your table? If so, have you tried to bind the control to Not([YourField])

[rohnds]

It is an unbound field. I like the option button to work the opposite. I intend to use the value using vba for something else.

So what code do you have in the option button that displays the available cars?
