[SOLVED] How do I iterate a table inside a table while also iterating through the first one?

local GROUPS_WITH_COLOR = {
    ["1"] = { 
        ["255"] = Color.Red
    };
}

I'm trying to make it so that it iterates through GROUPS_WITH_COLOR , then iterate through all tables inside that table. And check if the player is that rank in that group. If so, give them the color red. This was my attempt at this:

for i, v in pairs(GROUPS_WITH_COLOR) do
    print(v.v)
    local player = game.Players.LocalPlayer
    local Chat = player.PlayerGui.Chat.Frame.ChatChannelParentFrame.Frame_MessageLogDisplay.Scroller.ChildAdded:Connect(function(Frame)
        print(player:GetRankInGroup(2))
        if player:GetRankInGroup(v) then

        end
    end)
end

However, it errors. Anyone know how to fix this?
