Why didn't this projectile shoot again?

--This below is how you make it shoot multiple bolts. change x, 1 to any number you want.
        game.Debris:AddItem(x, 1)
        wait(0.25)
        for i = 1, 12 do

            Run.Stepped:wait(0.01)
        end

      --Heres how long you want it to be before you use it again change wait(2) to anything u want

      wait(1)
      --Here is how i made it able to work again after the time has run out "enabled = true"
enabled = true

     end


enabled = true
function onS(mouse) 
mouse.Button1Down:connect(function() onButton1Down(mouse) end) 
end 
bin.Selected:connect(onS)

Well it worked once, after that it won't work again.
