How do I set position of an object to random instance?

I'm trying to make a roguelike shooter and have the level generator implemented but can't spawn the player. I have red markers in the corners of each room and in the middle and want the player to start at a randomly chosen marker on the map. How do I randomly choose an instance and use it to spawn my player?

I've tried this:

On start of layout | Player > Set position to (Marker.X, Marker.Y)

Pick a random Marker instance

But it hasn't worked. I guess a better thing to ask would be how to reference the marker that was chosen?

That's correct, let's see a screenshot of how you set it up. The order is on start of layout, sub event : pick random instance of marker > action : set player to marker.

If you have the actual event set up correctly then the problem could be with a number of things, maybe the markers haven't been created yet when you go to pick one etc.

I don't think that it is because the markers aren't created because the game only knows its done generating after the markers have been created.

Check the following:

Layout is linked to the proper event sheet

Player sprite is created properly

Markers are created properly

Check visibiity of the player sprite (layers, zindex, visibility)
