Activating another scene's script?

Hello. I am using toolbars for the options menu in my game (difficulty, ship, etc.). How can I make it so that when a button is active, it activates a component in the NEXT scene? I could try to use "do not destroy on load" but that would also keep the GUI elements on the screen. Any ideas? Thanks.

You could store a static variable in a separate script. When the button is active, it messages the separate script, then you "Don't Destroy on Load" the separate script and have your scene script check in OnStart for that value. Then it can load/activate the required component.
