use of different states for buttons
I need help establishing a logic for using states. I want users to click on 4 different buttons. When that button is selected I want it to change color but when another button is selected I want a third color selected. I've used states the states tab to create these states, Normal, Visited, Selected.
How do I take advantage of this using triggers. I know this should be straight forward and simple but I can't seem to think of how to accomplish this. I've attached an SL file with the slide I'm working on. Any help would be greatly appreciated.
