I need help with a button?

This is what I want to have happen: When I mouse over a button I want a gradient glow to appear behind it. When I click on the button, I want the glow to change colors. I've created the button and two different gradient glows but I don't know how to make the action take place.

To hook actions to mouse behavior, use the Actions property in the Property window associated with the object.

Here's a short tutorial that may help:
