Ranktags not updating text?

Alright, so. I'm making this nametag system for a friend of mines; I've completed the system but the text to display the division will not change. No errors are being posted into the output, and nothing is appearing in the script. Any ideas?

local groups = {
	visitor = {
		name = "Outsider";
		teamName = "Outsiders";
	};
	main = {
		id = 10815075;
		name = "Imperium Romanum";
		teamName = "Rome"
	};
	subs = {
		[1] = {
			id = 12782082;
			name = "Julia Family";
			teamName = "Julia";
		};
		[2] = {
			id = 10815193;
			name = "Urbanae Cohortes";
			teamName = "Urbanae Cohortes";
		};
		[3] = {
			id = 12622845;
			name = "The Praetorian Guard";
			teamName = "Praetorian Guard";
		};
		[4] = {
			id = 12852424;
			name = "Lictor Guild";
			teamName = "Lictor Guild";
		};
	}
}

function convert(s)
	return "|| "..s.." ||"
end


game.Players.PlayerAdded:Connect(function(player)
	player.CharacterAdded:Connect(function(char)
		local tags = script.BillboardGui:Clone()
		tags.u.Text = player.Name
		for _,group in pairs(groups.subs) do
			if player.Team.Name:lower() == group.teamName:lower() then
				tags.g.Text = convert(group.name)
				tags.gr.Text = convert(player:GetRoleInGroup(group.id))
				break
			end
		end
		if player.Team.Name:lower() == groups.main.teamName:lower() then
			tags.g.Text = convert(groups.main.name)
			tags.gr.Text = convert(player:GetRoleInGroup(groups.main.id))
		end
		if player.Team.Name:lower() == groups.visitor.teamName then
			tags.g.Text = convert(groups.visitor.name)
			tags.gr.Text = ""
		end
		tags.g.TextColor3 = player.Team.TeamColor.Color
		tags.gr.TextColor3 = player.Team.TeamColor.Color
		tags.Parent = char.Head
	end)
end)

Yes, I made a function for the strings as my keyboard doesn't have them and I tend to stop working on them and do something else.

Cheers!
