how to make a part spawner but its spawns are random?

hi im trying to make a quick game. its a knock off of the classic game dodge the teapots of doom

my random generator works but not where i want it too

here is the code

local Hardness = 3
local rep = game.ReplicatedStorage
local Kill = game.ServerScriptService.Code

while true do
	wait(Hardness)
	local X = math.random(1, 342.72)
	local Y = math.random(1, 342.72)
	local Kill1 = Kill:Clone()
	local cloneone = rep.Cup:Clone()
	local clonetwo = rep.Cup:Clone()
	cloneone.BrickColor = BrickColor.Random()
	cloneone.Parent = game.Workspace
	Kill1.Parent = cloneone
	cloneone.Position = Vector3.new(X, 42.475, Y)
	wait(4)
	cloneone:Destroy()
end
