Workspace cannot be cloned server script help?

Don't mind this I just make it so that I can read the script better.

model = script.Parent.Parent--Indicates that the script interacts with the model the button is grouped with. messageText = "Regenerating Heli"--If you want a message to appear upon pressing, type it here.

message = Instance.new("Message") message.Text = messageText backup = model:clone() enabled = true

function regenerate() message.Parent = game.Workspace model:remove()

wait(0.001)--Change this number to display the regen message as long as you want in seconds.

model = backup:clone()
model.Parent = game.Workspace
model:makeJoints()
message.Parent = nil

script.Disabled = true
script.Parent.BrickColor = BrickColor.new(26)--Black
wait(0.01)--Change this number to change the time in between regenerations via the button, in seconds..
script.Parent.BrickColor = BrickColor.new(104)--Purple
script.Disabled = false
end

function onHit(hit) if (hit.Parent:FindFirstChild("Humanoid") ~= nil) and enabled then regenerate() end end

script.Parent.Touched:connect(onHit)
