I have attempted to use org-collector. Each time, including the example at
[Search domain orgmode.org] 
<https://duckduckgo.com/?q=org%2Dcollector%20worg+site:orgmode.org>orgmode.org/worg/org-contrib/org-collector-example.html 
<http://orgmode.org/worg/org-contrib/org-collector-example.html>
all columns except ITEM evaluate to the default error. The ITEM column 
does evaluate as expected.
