How do I script a toggle on and off button for trails?

Just developed a bit of code that can be run in a Local script, it creates all the necessary things to turn on/off a trail. oh and it also creates the Gui and the trail plus parts required.

Oh did i mention it also moves the trail just infront/around the players camera? it does that too! lol

as you see i got a little carried away lol oh well, onto the script.

Must be a LocalScript and put inside your StarterPack folder!

local Camera = workspace.CurrentCamera

--[[
Note this script creates a part and a trail inside And some attachment points for the trail
The script then makes a Gui TextButton inside the players PlayerGui folder and hooks up the 
Button to switch on/off the trail

The last bit is moving the part in a kinda random motion to show the trail

Not sure if this script will work online as in other players seeing the created parts other than the 
player that runs this script so it should ONLY run from within the studio But the button script should 
work online!

 i encourage yoiu to play around with the values but not before backing up first! :)

hope this helps! :)
