How do I make things spawn randomly around the layout?

I am making a small game and I want to have enemies spawn in from top, bottom, left and right. How can I make this random?

You can have System Spawn Object at position, then for the X and Y coordinates, use random(0, layout.width) and random(0, layout.height).

..If I understood..correctly...around the layout.capx

Thanks korbaach, that did work! Works now!
