David, et al:

If Transcript works like HyperTalk, this will not happen because "if there
is a field..." refers only to the current card, not the card containing the
control receiving the message:

I made a copy of my HC Home stack and placed the following handler in the
card script of card "User Preferences":

on testit
  if there is a card field "User Name" then put "Found It" else beep
end testit

>From the message window I type 'send "testit" to card "User Preferences"'.

If I'm on card "User Preferences", "Found It" appears in the message
window; if I'm on a different card, I get the beep.

IF it works this way in Transcript, I submit it is the best solution
because no explicit action is necessary to stop the loop when leaving the
card.
