Why does my Overhead Gamepass script not work?

I have a script where it gives an overhead UI. There are 2 versions of it, one that has a rainbow color and the other that is normal. I am trying to check to see if the player has the game pass and give them the rainbow color one. The code will not give me a rainbow. The weird thing is, when I change the ID to a different gamepass I own, it works. The way I get the gamepass is by going to the gamepass page and right-clicking "View Source" and find the "data-item-id" code.

Here is the code:

game.Players.PlayerAdded:Connect(function(Player)

    Player.CharacterAdded:connect(function()
    if game:GetService("MarketplaceService"):PlayerOwnsAsset(Player,4879950087) then
        local Tag = script.BHG:Clone()
        Tag.Parent = Player.Character
        Tag.Adornee = Player.Character:WaitForChild("Head")
        Tag.Frame.Rank.Text = Player:GetRoleInGroup(2973368)
        Tag.Frame.User.Text = Player.Name
        else
        local Tag = script.BH:Clone()
        Tag.Parent = Player.Character
        Tag.Adornee = Player.Character:WaitForChild("Head")
        Tag.Frame.Rank.Text = Player:GetRoleInGroup(2973368)
        Tag.Frame.User.Text = Player.Name
        end
    end)    
end)

Any help will be appreciated.
