Button help in Flash 5.5?

[darrell]

Alright, so I've got to create a simple animation for my computer animation class. All it consists of is a simple background and two simple buttons, and 5-6 pictures. I have to make it so that the left button scrolls backwards through the pictures and the right button scroll forward through the pictures. The script on the buttons currently are:

and the timeline looks like this:

When I put on the last action a gotoAndStop (1); action, it will go back to frame 1 with the first photo but then the button stops working instead of continuing with frame 1's actions. Also, whenever I add the same action but change it to the left_btn instead it will make the entire actions not work... Any ideas?
