Adding a Button to Template

[size=2]Let me start by saying I am a basic user of Flash MX (that is…I am trying to learn it). I recently purchased a flash template to create a flash website for a friend and begin understanding some more advanced options within Flash. After review of the template we determined that we needed another menu option. While I have been able to edit the buttons (i.e. wording) and change certain features I am unclear as to how to add another button with the same effects as the other four. I recently contacted the sellers of the template and they are willing to make the change for me for $20; however, they are not willing to provide me a guide of how they did it. Since the main reason I did this was to learn more about flash I was really hoping to find someone who could take a look at the flash and give me a guide on “how to”.

Any help you could provide is greatly appreciated!
