How can you enable a script that plays an animation?

So, the problem is that im trying to enable a script, but it doesnt...

Script (LOCALSCRIPT):

script.Parent.MouseButton1Click:Connect(function()
    **game.Workspace["The castle dungeon"].GuardF.Script.Disabled = false**
    script.Parent.Parent.Parent.HackyMouseMovementStuff.TextButton:Destroy()
end)

Script that i want to enable:

local hum = script.Parent.Humanoid
local Animation = Instance.new("Animation")
local plyr = game:GetService('Players').LocalPlayer
Animation.AnimationId = "rbxassetid://9320074412"


    print("Signal Successful!")
    local AnimationTrack = script.Parent.Humanoid:LoadAnimation(Animation)
    AnimationTrack.Priority = Enum.AnimationPriority.Action
    AnimationTrack.Looped = false
    AnimationTrack:Play()
    wait(0.6)
    script.Parent:Destroy()

Can anyone please help?
