Triggers are not working when revisiting a slide

Thanks for your reply :) The piece of information "A "when the timeline starts on this slide" trigger will run whenever the user visits the slide. That's true even if the slide is set to "Resume saved state. And that's why such a trigger usually needs conditions." was exactly the reason why it was not working. 

I was setting a state to change when a variable changed, but that variable was changing in a different slide. Therefore, I just changed that trigger to change state when timeline starts on this slide if my variable equals to 9. The number variable is working just fine :)
