I have replied to this problem in your other forum thread.

Please do NOT create multiple forum posts for the same problem.
That simply wastes the time of those of us who give up some of our free time to try to help fellow learners on the forums.

You might not get an immediate reply.
You could usefully use that “wait” time to:

  • re-read the instructions - have you followed them correctly?
  • Google search anything in the instructions you don’t understand
  • search the forums for similar problems

If , after an hour or two, you haven’t had a reply to your post, it may have been overlooked.
Just add a reply to your own post so that it appears higher in the list. and has more chance of being noticed.
