Data view list for noob

i tried to put it like the tutorials around youtube for a simple dataview list, but does not appear my list notes,only this. ( in preview and edit mode) can someone guide me? thanks.

Hi and welcome @Hid-rein71!
Have you installed the “dataview” community plugin by going to “Settings” → “Community Plugins”, enabling community plugins, and then browsing the list to find “dataview”? After installing dataview, did you enable it, check any settings you wanted to change in “Settings” → “Dataview” and then close and re-open obsidian?
Do you see in “Settings” a tab for “Dataview”?
