How to change values in the server side from StarterGui?

So I have a couple of values in workspace, I have a script in StarterGui that when you right click, the value changes. However, my value does not change. Am I doing something wrong? The weld break code works.

Code in starter:

local player = game.Players.LocalPlayer

local mouse = player:GetMouse()





mouse.Button2Down:Connect(function()

    if game.workspace.Values.have.Value == 1 then

        game.workspace.Values.have.Value = 0




        player.Character.Weld:Destroy()

    end


end)

Is there anything wrong??
