Saber throw can't figure out what the problem is? [closed]

So I have a problem im a star wars developer and my players have been asking me to add saber throw to the lightsabers here's a part of it .. Did I forgot something ?

function ThrowAttack()
    if throwing == true and enabled then
        candamage = true
        local saber = character:findFirstChild(ls)
        local throwingHandle = saber:Clone()
        DebrisService:AddItem(throwingHandle, 5)
        throwingHandle.Parent = game.Workspace
        for _, child in ipairs(throwingHandle:GetChildren("ManualWeld" and "EmitterWeld" and "SaberWeld")) do
        child:remove()
        end
        wait()
        throwingHandle.Handle.Velocity = (mouse.TargetPoint - saber.Handle.CFrame.p).unit * 100
        saber.Handle.SaberWeld.C0 = CFrame.new(saber.Handle.CFrame.p, saber.Handle.CFrame.p + saber.Handle.Velocity) * CFrame.Angles(0, 0, math.rad(-90))
        local floatingForce = Instance.new('BodyForce', saber.Handle)
        floatingForce.force = Vector3.new(0, 196.2 * saber.Handle:GetMass() * 0.98, 0)
        local spin = Instance.new('BodyAngularVelocity', saber.Handle)
        spin.angularvelocity = saber.Handle.CFrame:vectorToWorldSpace(Vector3.new(0, -400, 0))

        wait()
        if saber.Handle then
            local touchedConn = saber.Handle.Touched:connect(function(hit)
            saber.Handle.Velocity = (mouse.TargetPoint + saber.Handle.CFrame.p).unit * 100
            saber.Handle.SaberWeld.C0 = CFrame.new(saber.Handle.CFrame.p, saber.Handle.CFrame.p + saber.Handle.Velocity) * CFrame.Angles(0, 0, math.rad(-90))
            local floatingForce = Instance.new('BodyForce', saber.Handle)
            floatingForce.force = Vector3.new(0, 196.2 * saber.Handle:GetMass() * 0.98, 0)
            local spin = Instance.new('BodyAngularVelocity', saber.Handle)
            spin.angularvelocity = saber.Handle.CFrame:vectorToWorldSpace(Vector3.new(0, -400, 0))
            end)
        end
        wait(0.6)
        if saber.Handle and throwing then
            WeldParts(character["Right Arm"])
            saber.Handle.SaberWeld.C0 = CFrame.new(0,-1,0) * CFrame.fromEulerAnglesXYZ(math.rad(90),math.rad(180),math.rad(180))
            saber.Parent = character
            throwing = false
            candamage = false
        end
    end
end
