Thank you Jed for the specific examples. I knew how to substitute but wasn't aware of the 'inverse' syntax for the <$count> operation -- when noted as the <$count> widget I could never get it to work but putting it at the end of a <$list> filter as [count] does work exactly as needed.
Just for the record, here's my sample code -- by means of an example, this code returns a sum of tiddlers tagged as apples and oranges (so, 2 variables wrapped around the macro that's performing the calculation). The 'oranges' list still returns the full count as defined by its own filter, even though it's encapsulated within the 'apples' list filter. I guess that's because it's a count operation. \define Calculation() <<formula "$(apples)$+$(oranges)$">> \end <$list filter='[tag[apple]count[]]' variable='apples'> <$list filter='[tag[orange]count[]]' variable='oranges'> <<Calculation>> </$list> </$list> Thanks again!
