script receiving Arguments and parameters wrong using remote events. Help?

I got this following local script:

script.Parent.MouseButton1Click:connect(function()
	local ThePlayerName = script.Parent.Parent:WaitForChild("PlayerNameHere").Text
	script.Parent.Parent.Parent.Parent:WaitForChild("TotalBans").Main.UnBanPlayer:FireServer(ThePlayerName)
	print(ThePlayerName.."'s the player name that got sent!")
end)

And other following one:

script:WaitForChild("UnBanPlayer").OnServerEvent:connect(function(PlayerName)
	local points = 0
	for i,t in pairs (BannedPeople) do
		points = points + 1
		if t == (PlayerName) then
			table.remove(BannedPeople,points)
			print(PlayerName.." successfully removed!")
		end
	end
	points = 0
	---------
	advance = 0
	print(PlayerName.." Is the player name received!")

I keep getting this error: 15:52:49.478 - Players.wilsonsilva007.PlayerGui.AdminGui.Background.TotalBans.Main:37: attempt to concatenate local 'PlayerName' (a userdata value)

But when I changed the PlayerName to PlayerName.Name it just printed my username..

I just want the script to send a 'Name' and receive that 'Name'. Only that. And this is getting me annoyed..

With 'OnClientEvent' and 'FireClient' it worked well in studio but didn't work in game.. And I'm unsure what I'm doing wrong.

Help would be apreciated! Thank you very much for your attention!

P.S. I didn't pay much attention to Arguments and parameters so if this is a really stupid and dumb question I'm sorry. /:
