How do I assign an events sheet to a layout ?[Solved]

Hello world

I'm not sure i understood entirely the function of the layouts, and how a layout is assigned to an events sheet.

Is a layout equivalent to a game level ?

If yes, how do i assign multiples events sheets to multiples new layouts ? (One by one)

click on the layout in project view and it's the second option on the left side of the screen under layout properties

Thanks a lot volkiller730
