Why can't I access a ObjectValue inside of a ScreenGui?

I have a inventory system, and inside of that is a ObjectValue that is named Equipped. In my script, I want the code to fire ONLY when the player has an Axe equipped. However, the script is not detecting Equipped's value.

Here's my script. [ServerScript in a part]

local player = game.Players.PlayerAdded:Wait()
local character = player.Character or player.CharacterAdded:Wait()
while not character.Parent do
	character.AncestryChanged:Wait()
end
local Humanoid = character:WaitForChild('Humanoid')
local HRP = character:WaitForChild('HumanoidRootPart')

local mouse = player:GetMouse()

local Anim = Instance.new("Animation",script.Parent)
Anim.Name = "ChopAnim"
Anim.AnimationId = 'rbxassetid://3027147369'
local Animation = Humanoid:LoadAnimation(Anim)
local Part = script.Parent

local Equipped = player.PlayerGui:WaitForChild('BackpackGui'):WaitForChild('Frame').Handler.Equipped

game.ReplicatedStorage.PressedE.OnServerEvent:Connect(function()
	if Equipped.Value == "[LUMBERJACK] Axe" then
		if (HRP.Position - Part.Position).magnitude < 4.5 then
			Humanoid.WalkSpeed = 0
			Humanoid.JumpPower = 0
			Animation:Play()
		end
	end
end)

It's supposed to work, but isn't.

Can anyone help me please? I'm really desperate.
