A field value of "na" is equivalent to "0". I tried the above code on TiddlyWiki.com, providing it with a tiddler named "test", containing a "birth_year" field containing "na". After pressing the button, the "test" tiddler had a new "c_status" field added, containing a value of "retired". Note that to see this field and value, you have to edit the "test" tiddler. > I then tried the following code to create a list, but the tiddler still > shows nothing.

Without this, the result of the filter is the value that you get[...] from the birth_year field, rather than the title of the matching tiddler. Also, your first compare is "gteq[1]", so this would not match tiddlers where the "birth_year" field contains "0" (or "na"). If you change the filter to: <$list filter="[<currentTiddler>get[birth_year]compare:number:gteq[0]compare:number:lteq[1948]then<currentTiddler>]"> it will show tiddler titles for all tiddlers with a non-blank "birth_year" field, even those with a value of "0" or "na". enjoy, -e -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
