How do I make a condition be one or the other on Stateflow?

Hey all, I'm designing a traffic light system in Simulink using stateflow and need to know how to change a condition so it can be met with one of 2 conditions.

How do I put "button equals to 1 or 0" for the condition cirlced in red? As I need the traffic light system to run even if button doesn't equal to one but to jump to that line when button does equal to 1.
