Thanks for all comment and help.
Can you tell me what went wrong..... when I checked the uploaded videos I was directed to the right ones..... my own computer history????

3 posts earlier Mark fixed the Youtube links. If you edit his post you can see what he did to fix them.
Your (non-working) link:
https://www.youtube.com/edit?o=U&video_id=OSFHelpgwAU
Mark's fixed link:
https://www.youtube.com/watch?v=OSFHelpgwAU
You can clearly see what he did. Looking at your link, it appears that you posted a link for editing your videos, while Mark changed it to a link for watching the videos.
