I want to constantly check if the player is inside the area. Code stops when it checks.?

I want my code to constantly check if the player is inside the hitbox area. However, it stops when it checks for magnitude > 10, and I can't figure out why.

player = game.Players.LocalPlayer
	repeat wait() until player:HasAppearanceLoaded() == true
	while true do
		wait()
	local magnitude = (player.Character.UpperTorso.Position - game.Workspace.GetOn.Position).magnitude
	print(magnitude)
	if magnitude <9.9 then
		if player and script.Parent.getOnScriptMoved.Value == false then
		getOnScript = game.ServerStorage.GetOnFrame:Clone()
		getOnScript.Parent = player:WaitForChild("PlayerGui")
		wait()
		script.Parent.getOnScriptMoved.Value = true
	end
	elseif magnitude >10 then
		guiLocation = player:WaitForChild("PlayerGui")
		if guiLocation.GetOnFrame then
			guiLocation.GetOnFrame:Destroy()
		end
	end
	end

I figured out a way to recode this, and my problem has been resolved. I made two separate local scripts and put them inside StarterPlayer.StarterPlayerScrips, and messed with the code a bit. Here is what I put in each one to make it work.

player = game.Players.LocalPlayer
    repeat wait() until player:HasAppearanceLoaded() == true
        wait()
game.Workspace.GetOn.Touched:Connect(function()
	local magnitude = (player.Character.UpperTorso.Position - game.Workspace.GetOn.Position).magnitude
		if magnitude <9.9 and game.Workspace.GetOn.Value.Value == false then
		wait()
	        if player and game.Workspace.GetOn.Value.Value == false then
	       	 getOnScript = game.Workspace.GetOnFrame:Clone()
	       	 getOnScript.Parent = player:WaitForChild("PlayerGui")
	         wait()
	       	 game.Workspace.GetOn.Value.Value = true
			end
	    end
end)

player = game.Players.LocalPlayer
    repeat wait() until player:HasAppearanceLoaded() == true
        wait()
game.Workspace.Baseplate.Touched:Connect(function()
	local magnitude = (player.Character.UpperTorso.Position - game.Workspace.GetOn.Position).magnitude
		if magnitude >9.9 and game.Workspace.GetOn.Value.Value == true then
		wait()
	        if player and game.Workspace.GetOn.Value.Value == true then
	       	 getOnScriptParent = player:WaitForChild("PlayerGui")
	         getOnScriptParent.GetOnFrame:Destroy()
	       	 game.Workspace.GetOn.Value.Value = false
			end
		end
end)
