Try ensuring that the 'sharedText' property of your target fields are  
set to true.

If the sharedText is false, the field stores and retrieves its data  
from a card-local store, rather than its private store. Since  
'sending' a message only changes the default stack and not the  
current card of that stack, the active card store will be the card  
you aren't expecting.
