title: Discord bot problem "is a required argument that is missing"
body: <p>so basically I'm trying to make a youtube player command that will play audio through a voice chat and I've been testing the command and it keeps saying "dysfunctional (name of variable) is a required argument that is missing" and I am providing the link but it still says its missing, I may just be dumb but I'm almost positive this should be working</p>
  
  <pre><code>@client.command(pass_context=True)
  async def yt(self, ctx,*, dysfunctional):
      channel = ctx.message.author.voice.voice_channel
      if dysfunctional.startswith('https://www.youtube.com'):
          voice = await client.join_voice_channel(channel)
          player = await voice.create_ytdl_player(dysfunctional)
          player.start()
      if dysfunctional == "stop":
          player.stop()
          disconnect()
  </code></pre>
