Field calculations

[Geoff Canyon]

If you mean, "I changed the value in the loan percentage field, but nothing
happened," then check what Jim wrote above about the closeField message.
Whenever you change the value in a field, as soon as you click someplace
else the field gets a closefield message, and if the field (or the card the
field is on, or the stack the card is in) has a script like this:

on closeField
   answer "You changed something."
end closeField

then you'll get a dialog. From there you just need to get rid of the answer
command I used and put what you really want to have happen there.
