Where's the error in this script? [closed]

(First off, I dont know why the original was deleted...) And no, the output shows nothing...

local toolname = "Luger, Colt 45"  
script.Parent.Touched:connect( function(hit)   
    if hit.Parent then 
        local player = Game.Players:GetPlayerFromCharacter(hit.Parent)   
        if player and not player:FindFirstChild("No") then 
            if player.Character:FindFirstChild(toolname) then 
                local gui = player.PlayerGui.StoreRobberyGUI  
                local no = Instance.new("IntValue", player)  
                no.Name = "No" 
                Spawn(function()  
                    wait(10)  
                    no:Destroy()   
                end)  
            end 
        end 
    end 
end)   

I put this in the brick that I needed to touch it, the StoreRobberyGUI is the actual name of the GUI, but when I touch the brick holding one of the guns, it doesn't appear...
