getting This Error OpenScript:10: attempt to index local 'EnableShop' (a nil value) dont know why?

``I've been trying to Change Visible on a Frame when a player touches a part but its giving me this error and i don't know why.

The Error Workspace.DetectPart.OpenScript:10: attempt to index local 'EnableShop' (a nil value)

the script is a global script

here is my script

script.Parent.Touched:connect(function(hit)
	if hit.Parent:FindFirstChild("Humanoid")and game.Players:GetPlayerFromCharacter(hit.Parent) then
		local player = game.Players:GetPlayerFromCharacter(hit.parent)
			if player.OnPart.Value == false then

					player.OnPart.Value = true
					
					local EnableShop = player.PlayerGui:FindFirstChild("EnableShop")
					
					EnableShop.Frame.Visible = true	
		end
	end
end)

I've tried many different ways and i cant figure it out :(

If FindFirstChild doesn't find a child with the provided name, it'll return nil. I would recommend using WaitForChild instead, as it's possible the child hasn't yet been parented to the playergui by the time that line is reached.

E: Actually, it appears as if you're trying to read the content's of a player's playergui, which can't be done on the server. I originally thought you were using a localscript, however this doesn't appear to be the case.

script.Parent.Touched:connect(function(hit)
    if hit.Parent:FindFirstChild("Humanoid") and game.Players:GetPlayerFromCharacter(hit.Parent) then
        local player = game.Players:GetPlayerFromCharacter(hit.parent)
        if player.OnPart.Value == false then
			player.OnPart.Value = true
			local EnableShop = player.PlayerGui:WaitForChild ("EnableShop")
			EnableShop.Frame.Visible = true 
        end
    end
end)
