Hi David
In filters you can’t combine the effect of the [, { and < brackets. Instead
you’d have to extract the field value as a separate operation.
Try this (I’ve changed the tiddler and field names so that it works on
tiddlywiki.com <http://tiddlywiki.com/>):
<$set name="datasource" value="Commands">
<$set name="datasourcetext" value={{{ [<datasource>get[tags]] }}}>
<$list filter="[enlist<datasourcetext>]" variable="field-item">
<$text text=<<field-item>>/>
</$list>
</$set>
</$set>
Note that I also replaced <<field-item>> with <$text text=<<field-item>>/>. The
former will wikify the value of the field, so, for example, if it contains
double single quotes they’d be interpreted as starting bold text.
Best wishes
Jeremy.
