Sliding menu tutorial question


I have a question on the tutorial here “sliding menu” for flash8,

i’ve followed this tutorial to make a sliding content on a part of my scene and it works but then i made the same thing for another part of my scene and now the previous one doesn’t work, how do i have the same sliding content effect on a single page/scene in different parts?
I have no understanding of action script so i’m just copy pasting the code, just changing the instance names of my movie clips, please help what should i change to make all my content work?
