how do i randomly select something from a folder when a player touches a block?

right so i have 8 folders and a brick so when someone touches a brick I want it to randomly select something from the folder and put it into the workspace. At the moment I have this inserted in a brick and have no idea why it doesn't work.

function onTouch(part) 
	local humanoid = part.Parent:FindFirstChild("Humanoid") 
	--first room random
	local maproom1 = game.Lighting.Room1
	local chosenmap = maproom1[math.random(1, #mapsinserverstorage)]
	chosenmap:Clone().Parent = game.workspace.MapStorage
end

script.Parent.Touched:connect(onTouch)

nvm i sorted lmao
