How can I make an event in the workspace change something in the StarterGui?

I'm making a survival game right now, and I'm trying to make it so that when you break down a tree, it makes the picture of wood in the inventory space go from a dark, desaturated filter to a normal shade, as when the dark image is visible then the inventory cannot be accessed from that button. But when the tree breaks it just doesn't do anything. I have the script for the tree as a (script inside a model inside the workspace), and the second UI script as a (Localscript in a frame, in a screengui, in the startergui). I've tried swapping them (Localscript to a script and the other way around), and including both codes into one script while also changing their locations. This is the UI script:

``woodbutton.MouseButton1Click:Connect(function()
if nolog.Visible == true then
print("You have no logs")
else --(This is where stuff would happen)
    end
end)

and the Tree script:

local Log = script.Parent.Log
local Leaves = script.Parent.Leaves
local hits = 0
local totalhits = 8

Log.Touched:Connect(function(hit)
if hit.Parent.Name == "axe" then
    hits = hits + 1
if game.StarterPack.axe.Equipped == false then
    Log.Anchored = true
    Leaves.Anchored = true
else
    if hits == totalhits then
        hits = 0 Log.CanTouch = false
        Log.Anchored = false
        Leaves.Anchored = false
        Leaves.CanCollide = false
        wait()
        Log.Rotation = Vector3.new(45,0,0)
        wait(3)
        Log:Destroy()                game.StarterGui.GameGui.InvFrame.ScrollingFrame.WoodButton.ImageLabel.Visible = false           
            print("Logs obtained")
            end
        end
    end
end)

Please help me I have been asking this question fror 4 days and I don't know how to fix it.
