To check for changes you could write some code that checks each of the
fields using a loop or whatever.
Alternatively you could set a flag whenever some data is changed in each of
the fields actions blocks. Then you just
check the "dirty face" flag. The trick then is to capture the case that
someone has made a change in the field but it has not been flagged by the
action block code.

For a description and examples. But don't take everything there as gospel...
I'm still learning this stuff too. :)
Brett.
