"The Target" is the name of the field in the following format: field

And they say HyperCard was easier to learn? :)
What lexical logic drove such a decision? I would have loved to have
been a fly in the room during that meeting; it might help explain HC's
scrolling mechanism. ;)
The problem with your script could be that you have quoted the name
of the field but not the word "field" in front of it.
You might try something like:
if the target = ("field "&"e&"f_i_billoflading_specialNote""e)
These HyperCard-based ambiguities are among the hardest xTalk things to
teach, so chock full o' gotchas and sometimes rules that it's hard to
keep them straight.
While your suggestion does a good job of coercing the right-hand
expression to be evaluated as an object descriptor to match the
left-hand one, I tend to avoid these ambiguities altogether and use
property syntax instead:
if the long id of the target = the long id of fld "Whatever"
- or -
if the text of the target = the text of fld "Whatever"
This way anyone can read this code, and even without a decade of knowing
the mysteries of HyperCard's gotchas they can still instantly grasp
what's being compared, whether it's an object reference or the contents
of the object.
I love xTalk, but some of the decisions from the HC team continue to
mystify me, and continue to cost new learners time long after its demise....
