[development] Need another pair of eyes - page callback & form

[Jeff Greenberg]

What it turned out to be, after trying everything, was a combination of 
the url needing to be qualified, and apparently a collision with the 
original callback (I presume) existing somewhere else. When changed it 
from orders to orders_details in the callback and the action, it worked. 
Very odd that the action would not work with the original callback (even 
when the url became qualified) but the menu link would!

Thanks all!
