Trouble with Flash MX 2004 button navigation

Hello

This is my first time on this site and if I am posting this in the incorrect spot then please direct me elsewhere. I am trying to create simple button navigation in Flash MX 5. In the tutorial on your site and in the book I have checked out (the book is on Flash4 though) it says you can simply click on the button and then select Modify>Instance, choose the actions tab, and select from a variety of On (mouse event) actions. Flash MX 5 does not work like this and I have tried going in to the actions and selecting the action scipt commands by hand but I keep receiving script errors. I am fairly new to the program and the way the manual and a couple tutorials I have looked at make it seem rather simple to use buttons to navigate between scenes and frames of a flash document. I seem to be missing how to get to this simple mouse action/naviation menu. To me it seems they have actually made it harder not any easier in the transition from 4 to 5.

Thanks for any help you may be able to offer,
