Uploading musicto a forum

I have been trying to upload songs I have written, to a forum. I think I have followed the system to do this, but when I send the music using the link and a ‘Box’ number, no sound let alone music, arrives! I am rather elderly, so maybe I have overlooked something quite simple, but would really appreciate a clear method of doing it, please.

Many thanks, Ron

I have locked this topic, so please reply to one of those other topics if you require further assistance with using Audacity.
We cannot help you with using the Yamaha forum. That forum has nothing to do with us.
