Hi, I'm trying to learn IWB, and I'm struggling with "Example 2 – Templates and Widgets 1". The instructions say "…If we want to display this value in a generic way on the wiki page, we need to encompass the following piece of code with the $-symbol.

this.mondial:name ..."

I've tried several variations, such as $ this.mondial:name, $this.mondial:name,
$this.mondial:name$ and I can't seem to get the widget to work properly.

The widget code is ...

#widget: TableResult |
  query = 'SELECT ?Abbreviation ?Name WHERE {
            ?? mondial:isMember ?Organization .
            ?Organization mondial:abbrev ?Abbreviation .
            ?Organization mondial:name ?Name }
            ORDER BY ASC(?Abbreviation)'

Can you tell me what I'm doing wrong?
