Newbie question

So I’m making a project that has a title screen then when the play button is hit it starts to play a scene. There are also 2 other scenes that will be able to be played when those buttons are hit. I can’t figure out how to get this to work. Take a look at my file and let me know how to do it or send a file back if you have time.
