   I can adapt my app for that.

-botp,
 This is superb! I was reluctant to ask for help on this at all because 
it sounded so much like I was asking "write my code for me." But I would 
have never gotten that, because I did not know you could use sort_by in 
such a way-- passing an array as the last line of the block. It is 
exactly what I needed and I am most grateful-- for the clearer 
understanding (and the code :)

Thank You,
Howard
