function fire()
     local p = Instance.new("Part")
     p.Position = script.Parent.Position
--   p.Size = Vector3.new(2,3,2)
--   p.BrickColor = BrickColor.new(26)
     p.BottomSurface = 0
     p.TopSurface = 0
     p.Name = "TycoonBrick" 
     p.Parent = script.Parent

Edit this and put it in a Code Block so it's easier to read.
