Setting up a Button to start a Cut scene

Hello, I need help setting up a button to run an already made sequence I have setup:
Button1 and Testone(Sequence)
Inside the event graph for button one I go to On Click---->setplayback Position… from here I don’t know how to link it to play the sequence…Is anyone able to help me with this or point me in the direction of a tutorial that covers this?

Below is the closest tutorial I fond but I am unable to get to work
