Buttons not working in all scenes

Hi, I’ve got a canvas with a pause button attached that works in the first scene but not in any others. the canvas rendermode is screen overlay. Now I’m not destroying my camera on load but i am destroying the pause button canvas. I’m at a loss because the pause button is on the screen but when i go to touch it in the second scene but nothing happens.

In the hierarchy there should be a EventSystem object in the scene that works, if it is missing in the scene where it doesn’t work that is your problem as it is needed for unity to handle the touches/clicks.
