Targeting frame labels

I am trying to target frame labels in a single scene. I feel like I am doing it right but sometimes it works and sometimes it jumps to the final frame label.

Basically I have two buttons, each targeting separate frame labels in another layer. Once the movie is advanced to the targeted label then there are are “arrow” buttons that should navigate go back - go forward to change out the picture.

I have gotten help from a friend online who provided coding that worked but then the buttons I have for “go back” and “go forward” will not function. Is there any one who can tell me why it is not working? I am trying to do it without writing code. Just WYSIWIG. HELP! :jail:
