In game teaming script does not team besides specator?? Would love/need some help fixing it

game.Players.PlayerAdded:connect(function(player)
        if player:GetRankInGroup(2533886) == 8 then
                player.TeamColor = game.Teams.Security.TeamColor
        
                elseif player:GetRankInGroup(2533886) >= 1 then
                        player.TeamColor = game.Teams.Models.TeamColor

                        game.Players.PlayerAdded:connect(function(player)
                               elseif player:GetRankInGroup(2533886) == 0 then
                                        player.TeamColor = game.Teams.Spectators.TeamColor
                                
                                        game.Players.PlayerAdded:connect(function(player)
                                                elseif player:GetRankInGroup(2533886) >= 12 then
                                                        player.TeamColor = game.Teams.HighRanks.TeamColor                                           

Your code is very illegible. Your current code says if the player who joins' rank is >=1, then do your code, but if they are < 1, then it listens for a DIFFERENT player to join and do the same process? Use elseif.

Paste this in a LocalScript and place it in StarterPlayerScripts.

repeat wait() until game.Players.LocalPlayer
repeat wait() until game.Players.LocalPlayer.Character:IsDescendantOf(workspace)
