How would I select random items from a folder?

Hello, I would like to know how I can get the total amount of items inside a folder, randomly select them, and move them into game.Lighting. I’ve tried many different ways of scripting, but it still doesn’t seem to work the way I wish it would.

local count = 0

for i,v in pairs(workspace.Ambients.Triggers:GetChildren()) do
	count = count + 1 --finds the total number of items inside folder
end
local choice = math.random(1,count) --pick a random number of items
v.Parent = game.Lighting --move items into Lighting

Try This:

for i, item in pairs(workspace.Ambients.Triggers:GetChildren()) do
	local choice = math.random(1,#item)
    choice:Clone().Parent = game.Lighting
end

It errors with: attempt to get length of a Instance value

local items = workspace.Ambients.Triggers:GetChildren()
local randomItem = items[math.random(1, #items)]

That did work, but it only seems to move 1 of the items

6 
local items = workspace.Ambients.Triggers:GetChildren()
local randomItem = items[math.random(1, #items)]
local Folder = randomItem:GetChildren()
for i, ItemInFolder in pairs(Folder) do
	ItemInFolder:Clone().Parent = game.Lighting
end

To get the amount of items inside of a folder you can simply do:

Amount = #Folder:GetChildren()

The # is important.

To get a random amount of items use Random

local RandomAmount = Random.New():NextInteger(1,Amount)

Then move the items

for i,item in pairs(Folder:GetChildren()) do
if i <= RandomAmount then
item.Parent = game.Lightning
end
end

If this works please mark this as a solution, if it doesn’t, please tell me what went wrong

In the output, it displays: attempt to index nil with ‘NextInteger’

For this line:

local RandomAmount = Random.New:NextInteger(1,Amount)

Oops. I forgot to put the parentheses.
do this instead for that line:

local RandomAmount = Random.new():NextInteger(1,Amount)
