Shop Gui Won't Re Open Once Closed?

Whenever You Step On The Part It Opens/Tweens The Gui Perfectly, But Once You Close It And Try To Open It Again, It Doesn't Open?

It Might Because I Opened It From A Client And Closed It Locally, But I'm Not Sure How To Fix This?

Part Serverscript

CanOpen = true

function onTouched(hit)
    local plr = game.Players:GetPlayerFromCharacter(hit.Parent)
    if plr then
        if CanOpen == true then
            local shop = plr:WaitForChild("PlayerGui")
            local Main = shop.Main.PopUps.MainShopBag:TweenPosition(UDim2.new(0.298, 0,0.537, 0),nil, nil, 1)
            CanOpen = false
            wait(1)
            CanOpen = true
        end
    end
end

script.Parent.Touched:connect(onTouched)

GUI Close Script

script.Parent.Activated:Connect(function()
    script.Parent.Parent:TweenPosition(UDim2.new(0.298, 0,-0.537, 0), nil, nil, 1)
end)
