In order to construct wikitext syntax that inserts a value from a field,
you first need to create a macro definition, like this:
\define book-link(title) [ext[$(title)$|.\books\$(title)$.pdf]]
Then, to use it, you would write:
<$vars title={{!!book-title}}><<book-link>></$vars>
Let me know how it goes...
