How can I make this script's compability to be changed from R15 to R6 between the Lines in 7 and 12?

script.Parent.ClickDetector.MouseClick:Connect(function(player)
 local take = script.Parent.Parent.Taken
if take.Value == 'false' and script.Parent.Parent.Anim.Value == 'false' then
    take.Value = 'true'
    local box = script.Parent.JobBox:Clone()
    box.Anchored = false
    box.Parent = workspace:FindFirstChild(player.Name).RightHand

    local weld = Instance.new('Weld')
    weld.Parent = box
    weld.Part0 = box
    weld.Part1 = workspace:FindFirstChild(player.Name).RightHand
    weld.C0 = CFrame.new(1,0.5,0)
    script.Parent.Parent.Anim.Value = 'true'
    local char = workspace:FindFirstChild(player.Name)
    local flip = Instance.new("Animation")

            flip.AnimationId = "http://www.roblox.com/asset/?id=03571563488"
            flip.Parent = char
            local animloader2 = char.Humanoid:LoadAnimation(flip )
            animloader2:Play()
            script.Parent.Parent.Owner.Value = player.Name

while(1) do
    wait(1)
    if script.Parent.Parent.Anim.Value == 'false' then
    animloader2:Stop()

    end
end     

end
end)
