Appropriate syntax for referencing objects in a looping structure?

[Christopher Mitchell]

Opie,

Thanks for the reply.  well, yes, you're right that this works - and I 
would have sworn I had tried it, but I guess the confusion stems from 
the fact that in my regular format I have to use the quotes.  So I must 
have just been loading the variable wrong earlier when I was doing it 
before I looked up 'quote' ... :/  It seems weird to not put quotes 
when it is in a variable and to put them when it is not.

The shorter way is the first thing I tried!  I promise!  must have been 
4am typos or something.  Thanks again!

Yours,
Chris, the Newbie
