how to add several youtube videos into playlist and let it play automatically one by one??

I really have hard time figuring out how to make it

Simple!
While uploading there is a section on the right of the page as "add to playlist". If you have no playlist then click on "create a new playlist". Done! Add as many videos as you want to that playlist and then it automatically plays all the videos in that playlist.

I hope it helps.
