Anti team kill gun not working?

local tool = script.Parent
local player = game:GetService("Players").LocalPlayer
local t = player.Team
print(t)
 
tool.Equipped:connect(function(mouse)
	print("Tool equipped!")
 
	mouse.Button1Down:connect(function()
		print("Mouse pressed!")
		local ray = Ray.new(tool.Handle.CFrame.p, (mouse.Hit.p - tool.Handle.CFrame.p).unit * 300)
		local part, position = workspace:FindPartOnRay(ray, player.Character, false, true)
 
		local beam = Instance.new("Part", workspace)
		beam.BrickColor = BrickColor.new("Brick yellow")
		beam.FormFactor = "Custom"
		beam.Material = "Plastic"
		beam.Transparency = 0.25
		beam.Anchored = true
		beam.Locked = true
		beam.CanCollide = false
		
		beam.FrontSurface = "Smooth"
		beam.BackSurface = "Smooth"
		beam.LeftSurface = "Smooth"
		beam.RightSurface = "Smooth"
		beam.BottomSurface = "Smooth"
		beam.TopSurface = "Smooth"
 
		local distance = (tool.Handle.CFrame.p - position).magnitude
		beam.Size = Vector3.new(0.3, 0.3, distance)
		beam.CFrame = CFrame.new(tool.Handle.CFrame.p, position) * CFrame.new(0, 0, -distance / 2)
 
		game:GetService("Debris"):AddItem(beam, 0.1)
 
		if part then
			local humanoid = part.Parent:FindFirstChild("Humanoid")
 
			if not humanoid then
				humanoid = part.Parent.Parent:FindFirstChild("Humanoid")
			end
 
			if humanoid then
				if humanoid.Parent then
					local p = (game.Players:GetPlayerFromCharacter(humanoid.Parent))
					print(p.Team)
					if p == t then
						humanoid:TakeDamage(0)
					end
					else 
				end
			
				humanoid:TakeDamage(30)
			end
		    end
			
	end)
end)

t stores the players team and p is the targets team. It still damages players of the same team what matter what I do. Any idea? - Thanks
