I do it with my intranet apps.
Here's an example of the alert():
Missing/invalid data found.
Fix the fields with red arrows.
3 error(s) encountered:
Customer Name
City
State
I store thr value of the field's display name as
a hidden field then show that rather than the
field's internal (database) name; e.g. cusName.
If JavaScript isn't enable how are you doing
client-side validation? If you're only doing
server-side validation that down't the screen
refresh with the errors? (unless AJAX...)
