When I click, the fireball won't shoot. Why? Please Help.

Help This script doesn't work. This is in a script. Not a local one.

local Tool = script.Parent

 a:Play()
 root.CFrame = CFrame.new(root.Position.root.Position + Vector3.new(mousehit.lookVector.x,0,mousehit.lookVector.z)
 wait(0.7)
 local fireball = ToolHandle:clone()
 fireball.CFrame = Tool.Handle.CFrame
 local bv = Instance.new("bodyVelocity")
 bv.MaxForce = Vector3.new(1e8,1e8,1e8)
 bv.Velocity = mouse.hit.lookVector - 50
 bv.Parent = fireball
 fireball.Parent = game.Workspace

 fireball.Touched:connect(function(hit)
  if not ten then return end
