What do you consider to be a date? Would you put some
restraints on it?
e.g.:
isADateObject(formEntry) && isAfter(dateInPast)
&& isBefore(dateInFuture)

Create your own functions : isADate() and fieldsAreSame()
Then add to form tag:
<form
onsubmit=
"return document.MM_returnValue &&
isADate(this.dateField) &&
fieldsAreSame(this.field1,this.field2)">
You could modify the DW function, too. I could help you if
you let me
know your specs for date.
