The odd part is the the code it's complaining about is NOT executed at 
that point in time.. The liveCallback has already fired.. I've got 
breakpoints set in every block possible in that routine and NONE fire 
when I press the "submit" button on the main form.. This just doesn't 
make any sense to me..
