<$list filter="[has[yourfilter]count[]]" variable=result > <$reveal state="zerostate" type="match" text=<<result>>> NOTHING HERE FOLKS! </$reveal> <$reveal state="zerostate" type="nomatch" text=<<result>>> <<result>> </$reveal> </$list> (assumes you've made "zerostate" a tiddler populated with a "0". -- Mark On Saturday, July 28, 2018 at 10:48:43 AM UTC-7, Diego Mesa wrote: > > Hey mark, > > Good idea.
