Making a group and group rank leaderboard, run into issues. ?

So I want to make my friend's group a leaderboard that shows the person's division, i.e. another group, and then the rank of that group. I have this script, but when I start I see the leaderstats on the leaderboard but they do not fill in. I am in the first group on the list and it is still empty. It's in a regular script placed in ServerScriptService.

game.Players.PlayerAdded:connect(function(player) local leaderstats = Instance.new("IntValue")

leaderstats.Name = "leaderstats"
leaderstats.Value = 0
leaderstats.Parent = player

local allegiance = Instance.new("StringValue")
allegiance.Name = "Allegiance"
allegiance.Value = "None"
allegiance.Parent = leaderstats

local rank = Instance.new("StringValue")
rank.Name = "Rank"
rank.Value = "None"
rank.Parent = leaderstats


		
								--v----DDR/Divisions

if player:IsInGroup(3120627) then allegiance.Value = "DDR Volk." rank.Value = player:GetRoleInGroup(3120627)

elseif player:IsInGroup(2536151) then allegiance.Value = "DDR Grenz." rank.Value = player:GetRoleInGroup(2536151)

								--v----SAF/Divisions

elseif player:IsInGroup(2971335) then allegiance.Value = "SAF" rank.Value = player:GetRoleInGroup(2971335)

elseif player:IsInGroup(3294006) then allegiance.Value = "SAF Airborne" rank.Value = player:GetRoleInGroup(3294006)

elseif player:IsInGroup(3279476) then allegiance.Value = "SAF Airforce" rank.Value = player:GetRoleInGroup(3279476)

elseif player:IsInGroup(3279454) then allegiance.Value = "SAF KGB" rank.Value = player:GetRoleInGroup(3279454)

elseif player:IsInGroup(3120627) then allegiance.Value = "SAF Armor" rank.Value = player:GetRoleInGroup(3120627) end

		leaderstats.Parent = player

end)

This would be the proper way of handling it:

local values = {
	{3120627, "DDR Volk."},
	{2536151, "DDR Grenz."},
	{2971335, "SAF"},
	{3294006, "SAF Airborne"},
	{3279476, "SAF Airforce"},
	{3279454, "SAF KGB"},
	{3120627, "SAF Armor"}
}

game:GetService("Players").PlayerAdded:connect(function(player)
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	leaderstats.Value = 0
	local allegiance = Instance.new("StringValue")
	allegiance.Name = "Allegiance"
	allegiance.Value = "None"
	allegiance.Parent = leaderstats
	local rank = Instance.new("StringValue")
	rank.Name = "Rank"
	rank.Value = "None"
	rank.Parent = leaderstats
	leaderstats.Parent = player
	
	for i = 1,#values do
		if player:IsInGroup(values[i][1]) then
			allegiance.Value = values[i][2]
			rank.Value = player:GetRoleInGroup(values[i][1])
		end
	end
end
