1) You shouldn't need to wikify the $artworkID$
2) In your second list filter, you reference $(artID)$ ... but that is
incorrect, since the $(...)$ form of reference is only for variables that
are defined *outside* of the current macro.
3) Try re-writing your filter like this:
> <$list filter="[tag[Names]!tag[Index]!match<currentTiddler>
> search:artwork_id[$artworkID$]]">
