Lua Using function for 2 floors

[Santi]

So, I want it so it removes all players in an area, thats why im using this function:

local persons = getSpectators({x=EDIT, y=EDIT, z=EDIT}, 10, 10)

But how can I do it so it gets the player from upper/down floors to?
Thanks in advanced and rep+

EDIT: Nvm, solved, this thread can be closed.
For anyone that needs it:
getSpectators(centerPos, rangex, rangey[, multifloor = false])
