Help...buttons trigger unwanted sound

i’ve got sound in both scene 1 & scene 2, and i’ve some buttons in scene 2. When i click on those butons, the sound in scene 1 (or sometimes the sound in scene 2) was triggered and played, the more buttons i click, the more sound played…they overlap like mess. what’s the problem and how can i get rid of it? it’s urgent, thanks!

re:the buttons will go to a single frame that doesn’t include the sound layer
