Evaluating that form gives me:

Debugger entered--Lisp error: (void-variable somevalues)
  (assoc str somevalues)
  (cdr (assoc str somevalues))
  eval((cdr (assoc str somevalues)))
  skeleton-internal-1((cdr (assoc str somevalues)) nil nil)

I'm not at all familiar with how skeleton works, but a test case that
works would help when trying to debug.  :-)
