My custom chat isn't working right?

It works, but it doesn't display other player's chat. I'm not sure how to fix this, but it's a problem. Help?

local plr = game.Players.LocalPlayer

plr.Chatted:connect(function(msg)
    local p = game.Players:GetChildren()
    for j = 1, #p do
        local frame = p[j].PlayerGui.ChatGui.Chat
        local chat = Instance.new("TextLabel", frame)
        local l = frame:GetChildren()
        for i = 1, #l do
            if l[i].ClassName == "TextLabel" then
                l[i].Position = l[i].Position-UDim2.new(0,0,0,25)
            end
        end
        chat.Position = UDim2.new(0,0,1,-25)
        chat.Size = UDim2.new(1,0,0,25)
        chat.BackgroundTransparency = 1
        chat.TextStrokeTransparency = 0.3
        chat.TextColor3 = Color3.new(1,1,1)
        chat.TextScaled = false
        chat.Font = "SourceSansBold"
        chat.FontSize = "Size24"
        chat.Text = "["..plr.Name.."]: "..msg..""
        chat.TextXAlignment = "Left"
        chat.TextWrapped = true
        chat.TextScaled = true
    end
end)
