Thank you for the explanation! That helped me understand what's going on 
in the collect better. Yes, name is defined.  This is actually from a 
rails app and colors is the table which has a name attribute (among 
others), so this line works great if I want to show all the colors.  In 
another post a few minutes ago, I explained how I am actually using this 
in a call to another function from in ajax_scaffold.  I was trying to 
simplify it somewhat to get at the core of the problem, but I think in 
my lack of understanding, I simplified too much


Cheers,
Rosina
