Date form - checks for more than 28 days Feb

[Scott]

if (Month==1) && Day > 29 {
alert ("You can't have more than 29 days in February)

This works as long as the day is entered before the month, however, when
someone enters February with a null (99) date, it returns this error before
the person has had a chance to enter the date.

Is there a simple way to amend the above to give the alert is month is
February and date is greater than 29, but not 99 (ie blank)?

Thanks.

Easier to replace it w/ a date picker script
2/29 is not the only invalid date combo you need to check for
