I've been looking at variables in relation to editing a form. It doesn't seem so but is it possible to have a dynamic lookup of stored values during editing?

Something like

If $source==FOO then $period=BAR (where source is the name of an already stored page; and BAR is the value of a property on the FOO page)

and have the wiki to automatically add and display BAR as the value of the property period.

(Example: When adding a new recipe and entering the name of an existing recipe source, the wiki would insert the age of the source in the active form at a designated point.)
