I don't think I used instance variables for referencing the address book
entries, but the last guy always wins.  The screen of the guy who first
clicks on the next button will not display anything until the screen of the
guy who clicks later finishes.

notice if 2 different users try to access the address books, last one who
clicks on the button always get what it should display.  This sounds very
like they are both are using the same Action.
