"fil2" was missing a right square bracket. In addition, you're attempting to pass a filter to a filter. You can do this if you use the subfilter operator. You also need to terminate your text widgets with a final slash (/). So we end up with this:
<$set name="fil1" filter="[tag[tag1]]"> <$set name="fil2" filter="[subfilter<fil1>]+[tag[tag2]]"> <$text text=<<fil1>>/> <$text text=<<fil2>>/> </$set> </$set> On Sunday, January 17, 2021 at 1:13:00 PM UTC-8 [email protected] wrote: > > Hi all, > > I want to store the output of a filter in a variable and use that variable > later in a second filter to narrow the result down, and so on. > > In preparation I made several test tiddlers with both tag1 and tag2 as > tags.
