Make your life easier -- either take everything after the first 
character or use leading zeroes on your id numbers, e.g. q01 through q99.

One of my pet peeves is pages that run continuous javascript timeout 
loops, gobbling great gobs of CPU cycles, usually for little benefit 
except to strut the developer's stuff.  If you do go this route, 
please build in a natural termination for the process so it doesn't 
just continue as long as the page is loaded, or only runs while the 
page has focus.  Especially in these days of tabbed browsing it's 
cruel and unusual punishment to design pages that assume they are the 
only thing on the visitor's desktop, particularly noticeable with 
self-starting audio.

Regards,

Paul
