(SOLVED BY ME)Why does my BillboardGui not display "Guest" for people not in a specific group?

I made a script that clones a billboardgui from lighting and puts it inside the player's head when they join. Players can also use "!toggle" to turn it on and off. So far the script works to change the text of the GUI to their name and role in the group, but when players not in the group join, it just says "Label". I have an else statement to display a player's name, and then say "Guest" after if they aren't in the group, but it doesn't work. Any help would be appreciated. Note: There were no output errors.

local billboard = game.Lighting.BillboardGui:Clone()
local function giverole(p)
    local char = p.Character
    local role = p:GetRoleInGroup(5629879)
    local billboard = game.Lighting.BillboardGui:Clone()
    billboard.Parent = char.Head
    wait(0.1)
    if p:IsInGroup(5629879) then 
            billboard.TextLabel.Text = p.Name ..", " .. role 

    else 
            billboard.TextLabel.Text = p.Name ..", Guest"
    end
        local toggled = false
        p.Chatted:Connect(function(msg)
            if msg:sub(1,10) == "!toggle" and toggled == false then
                toggled = true
                char.Head.BillboardGui.Enabled = false
            elseif msg:sub(1,10) == "!toggle" and toggled == true then
                    toggled = false
                    char.Head.BillboardGui.Enabled = true   
                end

        end)
end
game.Players.PlayerAdded:Connect(giverole)
game.Players.PlayerAdded:Connect(function(p)
    p.Changed:Connect(function (property)
        if (property == "Character") then
               giverole(p)
        end
    end)
    end)
