I only want 1 force field in the character at a time. How do I check for this? Btw this is in a local script.~~~~~~~~~~~~~~~~~

local Player = game.Players.LocalPlayer
local Character = Player.Character
local Mat = workspace.Mat


local FF = Instance.new("ForceField")
FF.Parent = Character


Mat.Touched:connect(function(Part)
	if Part.Parent:FindFirstChild("Humanoid") and Part.Parent:FindFirstChild("ForceField") then
		local FF = Part.Parent:FindFirstChild("ForceField")
		FF:Destroy()		
	end
	
end)



function InsertFF(Part)
	if Part.Parent:FindFirstChild("Humanoid") then
		local FF = Instance.new("ForceField")
		FF.Parent = Character
	end
end

workspace.Baseplate.Touched:connect(InsertFF)
workspace.Floor.Touched:connect(InsertFF)
workspace.Step1.Touched:connect(InsertFF)
workspace.Step2.Touched:connect(InsertFF)
