I just put on an AS3 tutorial on how to make buttons and also selected my icon and image today. Look out for AS2 tutorials with enabled work for Flash 7+ instead of Flash CS3+. AS3 Button Tut requires Flash Player 9 or higher, Adobe Flash CS3 or higher, and a working computer to use. The ending actionscript is not just copy and pastable, but also editable by making the AS copy and paste an input text box.

AS3 Text Box Tip:

You cannot use Variables on Text Boxes in Actionscript 3 unless they are on the frame.
