Gui Is Not Working?

**What I Want ** : When you click the button if the model does not have the stated shirt Id then it will be destroyed and will create the shirt Id, But it dosen't work as seen.

ScriptIt's a local script in a Gui Button Btw

Subject = game.Workspace.Noob
Select = script.Parent.Parent.Selected
Player = Subject
Character = Subject
module3D = require(script.Parent.Parent.Parent.Parent.Parent.Module3D)
guy = workspace.Noob
Model = game.Workspace.Camera:WaitForChild("Item")
Thing  = Model:FindFirstChild("Shirt")


function Check()

    if Model:FindFirstChild("Shirt") then
         if Model.Shirt.ShirtTemplate == "http://www.roblox.com/asset/?id=201164991"
        then

        else
            Model:Destroy() 
        end

else

    Model:Destroy() 
    end

end



script.Parent.MouseButton1Down:connect(function()

if Character:findFirstChild("Shirt") then
Character.Shirt.ShirtTemplate = "http://www.roblox.com/asset/?id=201164991"
else
local Shirt = Instance.new("Shirt")
Shirt.ShirtTemplate = "http://www.roblox.com/asset/?id=201164991"
Shirt.Parent = Character
end 
script.Parent.Parent.Parent.Parent.Parent.LocalScript.Disabled = true
wait(.5)
script.Parent.Parent.Parent.Parent.Parent.LocalScript.Disabled = false
wait(.5)
Check()



end)

Problem It dose not change the shirt Id, nor deleted the model.
