Would this global function to get maps and spawn them in at random work?

This script should globally call maps however I recieve an error when running it.

function _G.GetMaps() -- can now be used in any other server script
	local maps = game.ServerStorage.Maps:GetChildren()
	
	for _,v in pairs(maps)do
	local randommap = math.random(v)
	x=randommap:Clone()
	x.Parent = game.Workspace
	local m = Instance.new("Message", workspace)
	m.Text = (x.Name.. " is the current map!" )
	wait(3)
	end
end

any and all help appreciated

Error I recieve when running the script
