Flash Button Glowing

[alpha202ej]

Morning!

I am making a flash movie, and I can’t quite get this button to do what I need it to. This button is at the end of the movie, and I want it to change colors to make it look like it's pulsing. It’s made as a button symbol, and has an shape tween effect to make it turn from blue to red and then back to blue. All I need it to do now is to repeat at the end of the movie continuously. Would this be accomplished through action script?

Thanks in advance
