Hi John, Try building the whole @FILTER Metatag dynamically as one big complete string using <@LITERAL>, then call the generated string with ENCODING=METAHTML, something like:
<@ASSIGN local$myCustomFilterMetatag VALUE="<@LITERAL VALUE='<@FILTER ...custom expr...>'>"> <@VAR local$myCustomFilterMetatag ENCODING=METAHTML> Hope this helps. Cheers....
