Moveclip and Actionscript problems. (MX 2004)

Hello.

I am a noob to actionscript (not a lot of experience in Flash either) and need some help.

What I am trying to do is get a button to make a movieclip go to a specific frame.
I have a movieclip that plays a set of frames up to the 100th frame, and then I tell it to go back to and play frame 1 again. However, at about 105, I have another set of frames that I want to play at the push of a button. How would I go about doing this?

Thanks.
