Code Snippets timeline navigation not working

Hi all!

I'm working on an animation project for a class. I'm trying to use code snippets (we've been instructed not to use action script) to utelize the timeline navigation "Go to frame and stop/play" and it works on the first button, however, when I try to apply the same code snippet on a different frame to a different button it doesn't work. I am changing the frame number it should go to and I made an instance name for each new button. Does anyone have any suggestions as to why this isn't working?

side note: I've also tried using the action "stop a movie clip" for a different button in order to end stop the audio and that also doesn't work. 

Any help would be greatly appreciated! Thanks 🙂
