Getting the format right using -reshape is not that easy. 
You could use -mimstack- to take care of that. You can 
install it by typing in Stata: -ssc install mimstack-.

There are also discussions of -mimstack- in John B. Carlin,
John C. Galati and Patrick Royston (2008) "A new framework 
for managing and analyzing multiply imputed data in Stata"
The Stata Journal, 8(1): 49--67
