Hi, again, Alex,

Actually, there is a perhaps more sensible solution where you don't store
that computed result into a field at all, but rather store the formula for
it in that field using the *eval* *widget*, e.g.:
title: Carbo-needs
kcal-per-day: 2500
carbs-percent: 45
kcal-carbs: <$eval>{{Carbo-needs!!kcal-per-day}}*{{Carbo-needs!!carbs-
percent}}/100</$eval>
And then, in any tiddler, do...
{{Carbo-needs!!kcal-carbs}}
Best wishes,
Tobias.
