Thanks to Jed Carty my first question was answered realy quick. And I could continue my work.
Now I got a new problem: I'm trying to double transclude text. Let me explain:
First Tiddler got field "a" with value "x"
Second Tiddler got field "b" with value "First Tiddler"
Now I want to get the value x in the second tiddler. I tried
but it does not work.
Afterwards I tried
<$set name="test" value={{!!b}}>
{{<<test>>!!a}}
</$set>
But this doesn't work either. Is there a way to double transclude with field values, where a field value contains the name of the transcluded Tiddler?
Kind regards,
Alex
