Buy button for shop won't update correctly, how do I fix??

So, in my game, I have a shop. The buy button is supposed to update to "Equip," "Equipped," etc, but it doesn't work right. Even if the player's equipped value is a certain skin, it won't say equipped! Client - side script:

boxName:GetPropertyChangedSignal("Value"):Connect(function()

    local model = nil

    for i, object in pairs(game.Workspace.Shop.ItemRoller["Box"..boxName.Value]:GetChildren()) do
        if object:IsA("Model") then
            model = object
        end
    end

    local toolsBought = game.ReplicatedStorage.GetSkinsBought:InvokeServer()

    for i, tool in pairs(toolsBought) do
        if tool == model.Name then
            script.Parent.Text = "Equipped"
        else
            script.Parent.Text = "Equip"
        end
    end

    print(script.Parent.Text)

end)

(The parent is the button.)

Server - side:

game.ReplicatedStorage.GetSkinsBought.OnServerInvoke = function(player)

    local tools = {}

    for i, tool in pairs(game.ServerStorage.PlayerSkins[player.Name]:GetChildren()) do
        table.insert(tools,tool.Name)
        print(tool)
    end

    return tools

end
