button issue

Hi Ziad zziadagamy ,

Can you post a screenshot if the issue (full UI, if possible), please?

A timestamp of what you are refering to in the video is often also very helpful.

Even extra helpful would be if you provide a link to your blend file so we can see if there's any issues with the mesh. 

Hi Jonathan Jojo ,

It should be: I to Inset, pull down and then E to Extrude (up) again.

What you appear to have done here is I, E(xtrude), pull down, or maybe I, I, pull down.
