Why didn't this projectile shoot again?

      --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.
