* The syntax surrounding a "filtered transclusion" is: {{{ [...filter goes

* Within filters, use SINGLE curly braces to fetch the contents of a
tiddler.
* Since there is no matching </$text>, use "/>" to end the $text widget.
Thus:
<$text text={{{ [{Tiddler}divide[2]] }}} />

The mathematical relationship between these numbers is not clear. If you
can provide an equation that shows how each input value gives the
corresponding output value, I can probably show you how to write it as a
filter.

* The keyword for the is[...] filter should be "blank", not "empty". Thus:
<$text text={{{
[{stateTiddler}is[blank]then[defaultText]else{stateTiddler}] }}} />
* You can simplify the above as:
<$text text={{{ [{stateTiddler}else[defaultText]] }}} />
