So, my script isn't working correctly, and here is the error message: 12:12:56.235 - Addid is not a valid member of ScreenGui 12:12:56.236 - Script 'Players.Player.PlayerGui.MusicLibrary.Menu.HistoryFrame.His', Line 2 My script is this:
script.Parent.MouseButton1Down:connect(function()
if script.Parent.Parent.Parent.Parent.Parent.Parent.Addid ~= nil then script.Parent.Parent.Parent.Parent.AddSongName.Visible = true script.Parent.Parent.Parent.Parent.Parent.Addid.Value = script.Parent.Parent.Parent.Text script.Parent.Parent.Visible = false
end
end)

On the next line: script.Parent.Parent.Parent.Text
Does your GUI have "Addid" as a textlabel or something similar?
It is a string value.
