Why isn't Player:DistanceFromCharacter working?

local player = game.Players.LocalPlayer
local runService = game:GetService("RunService")
local guiPart = workspace.MultiplayerComingSoon

local nearPart = false

runService.RenderStepped:Connect(function()
	if player:DistanceFromCharacter(guiPart.Position) < 2 then
		nearPart = true
		workspace.MultiplayerComingSoon.BillboardGui.TextLabel.Visible = true
	else
		nearPart = false
		workspace.MultiplayerComingSoon.BillboardGui.TextLabel.Visible = false
	end
end)

I started scripting a couple weeks ago, I've been kind of off and on and haven't really focused on learning much since I started. Anyways, I'm trying to make it to where a text label pops up saying "Multiplayer is coming soon" when the player is near a part used for multiplayer. I've read up on it a little bit and I've seen all this magnitude stuff, not sure how to go about it. Any suggestions on making this work?

dont even need DistanceFromCharacter just do this.

local player = game.Players.LocalPlayer
local runService = game:GetService("RunService")
local guiPart = workspace.MultiplayerComingSoon

local nearPart = false

runService.RenderStepped:Connect(function()
    if (player.Character:WaitForChild("HumanoidRootPart").Position - guiPart.Position).Magnitude < 2 then
        nearPart = true
        workspace.MultiplayerComingSoon.BillboardGui.TextLabel.Visible = true
    else
        nearPart = false
        workspace.MultiplayerComingSoon.BillboardGui.TextLabel.Visible = false
    end
end)
