My team script doesn't work correctly?

my script doesn't work because I said if the player is rank 0 like not in the group he should be civilan team but he still spawn as a enlisted how do I do so that the player that is not in the group spawns in civilan team

game.Players.PlayerAdded:connect(function(P)
    repeat wait() until P:findFirstChild("leaderstats")
    local Rank = Instance.new("StringValue", P.leaderstats)
    Rank.Name = "Rank"
    Rank.Value = P:GetRoleInGroup(2671856)
end)

game.Players.PlayerAdded:connect(function(newPlayer)
    local rank = newPlayer:GetRankInGroup(2671856) ---- Change that number to the ID of your group
    local teamName = ""
    if rank == 255 then 
        teamName = "Officer [O1-O10]" 
    elseif rank == 17 then
        teamName = "Officer [O1-O10]"
    elseif rank >= 16 then
        teamName = "Officer [O1-O10]"
    elseif rank >= 15 then
        teamName = "Officer [O1-O10]"
    elseif rank > 14 then
        teamName = "Officer [O1-O10]"
    elseif rank > 13 then
        teamName = "Officer [O1-O10]"
    elseif rank > 12 then
        teamName = "Officer [O1-O10]"
    elseif rank > 11 then
        teamName = "Officer [O1-O10]"
    elseif rank > 10 then
        teamName = "Officer [O1-O10]"
    elseif rank > 9 then
        teamName = "Officer [O1-O10]"
    elseif rank > 8 then
        teamName = "[E1-E9]"
    elseif rank > 7 then
        teamName = "[E1-E9]"
    elseif rank > 6 then
        teamName = "[E1-E9]"
    elseif rank > 5 then
        teamName = "[E1-E9]"
    elseif rank > 4 then
        teamName = "[E1-E9]"
    elseif rank > 3 then
        teamName = "[E1-E9]"
    elseif rank > 2 then
        teamName = "[E1-E9]"
    elseif rank > 1 then
        teamName = "[E1-E9]"
    elseif rank > 0 then
        teamName = "Civilan"


end
    newPlayer.TeamColor = game.Teams[teamName].TeamColor
end)
