Thread:Extension talk:Widgets/Not working

Hi, I'm traing implement widgets as "Disqus" or "Facebook like" without success but with any error. Where I make mistake?

I created for example searching the page Widget:DISQUS and I clicked create page with this name. Ok. Now what code I must copy in this page Widget:DISQUS?

This? or This? or or This?

and then? In a specific page (Ex: Testing) what code I must copy?

This? or This? or or This?
