Are you using the callbacks fullpage.js supplies. If not refer to the documentation there are callbacks supplied where you place events that you want to trigger linked to scrolling through sections and slides. If you are using the callbacks make sure you are using adequate specificity in your selectors to make sure that your scripts are running on items only contained within the slide/section you are targeting. ie if you simply select items on the dom the scripts will run your animation the first time or every time you scroll and the callbacks are invoked, regardless of whether the items are in the section you are scrolled to, selectors have to target the section you are in and the dom element you want to fire the event on.
