How can I make this include a tag?

So I basically want it to be able to automatically add the rank and I'd manually add the groups as seen below.

If anyone could help me out with what is wrong with this, that would be very helpful! :)

if Player:IsInGroup(2535914) then
	newName.Name = "[LEGV][" .. Player:RoleInGroup(2535914) .. "] "and  .. Player.Name

1. You need an "end"
2. Who is "Player"?
3. What is "newName"?
4. Why does it have an "and" when it there isn't even an if statement on line 2.

game.Players.PlayerAdded:connect(function(Player)
	if Player:IsInGroup(2535914) then
	    newName.Name = "[LEGV][" .. Player:RoleInGroup(2535914) .. "] ".. Player.Name --What is "new name?"
	end
end)

Try this with a function:

function newName(StatName, char) --Edit this part.
	local billboard = Instance.new("BillboardGui", char)
	local name = Instance.new("TextLabel", billboard)
	name.BackgroundTransparency = 1
	billboard.Size = UDim2.new(0,1,0,1)
	name.Text = StatName
end

game.Players.PlayerAdded:connect(function(Player)
	if Player:IsInGroup(2535914) then
	    Player.NameDisplayDistance = 0
	    newName("[LEGV]["..Player:RoleInGroup(2535914).."]"..Player.Name, Player.Character)
	end
end)

Hope this helps. You had a lot of errors.
