Gate model using GUI and normal script runs in studio but not client. Can someone help me?

Hi fellow Scripters

I have a gate model that I am having trouble with. It runs on studio mode but not on ROBLOX Client.

Here is the model: https://www.roblox.com/library/582381368/New-Gate-WIP

It runs on normal script. Not local script. I have done many stuff. Followed a few guides and yet turn out the same.

There are two scripts. Open and Close

Here is the Open Script

-- Variables --
opening = false
right = script.Parent.Parent.Parent.Parent.Parent.GateRight
left = script.Parent.Parent.Parent.Parent.Parent.GateLeft
open = script.Parent
close = script.Parent.Parent.Close
button = script.Parent



-- Main -- 
function onClick()
    if opening == false then
        opening = true
        open.Visible = false
        for i = 1,90 do

            for i,v in pairs( right:GetChildren() ) do
                v.CFrame = v.CFrame + Vector3.new (-.2,0,0)
            end

            for i,v in pairs( left:GetChildren() ) do
                v.CFrame = v.CFrame + Vector3.new (.2,0,0)
            end

            wait(0.01)
        end
        opening = false
        close.Visible = true
    end
end

button.MouseButton1Click:connect(onClick)

And here is the close script:

-- Variables --
closing = false
right = script.Parent.Parent.Parent.Parent.Parent.GateRight
left = script.Parent.Parent.Parent.Parent.Parent.GateLeft
button = script.Parent
open = script.Parent.Parent.Open
close = script.Parent



-- Main -- 
function onClick()
    if closing == false then
        closing = true
        close.Visible = false
        for i = 1,90 do

            for i,v in pairs( right:GetChildren() ) do
                v.CFrame = v.CFrame + Vector3.new (.2,0,0)
            end

            for i,v in pairs( left:GetChildren() ) do
                v.CFrame = v.CFrame + Vector3.new (-.2,0,0)
            end

            wait(0.01)
        end
        closing = false
        open.Visible = true
    end
end

button.MouseButton1Click:connect(onClick)

Please do help.Your help is appreciated.
