Help With Regeneration Script

[Ming-Yan]

I think it's a ROBLOX conversion error.

[lua]model = game.Work.BLUE
messageText = "REGEN BLUE SPIRE"

message = create("Message")
message.Text = messageText
backup = model:clone(BLUE)

while true do
sleep(10) -- regenerate this model every 300 seconds

message.Parent = game.Work
model:remove(BLUE)

sleep(4) -- display regen message for 4 seconds

model = backup:clone(BLUE)
model.Parent = game.Work
model:makeJoints()
message.Parent = nil
end
[/lua]
