Thank you so much John. This does allow me to limit the entry to a great
then-equal to value. However what I am trying to accomplish is settting a
time within a timesheet which limits the employee to a meal break of at least
30 minutes. This procedure you describe only allows time to be 30 minutes, it
doesn't allow anything over, i.e, if they clock out at 12 noon it won't allow
them to clock back in unless it is 12:30. I only want it to stop them if they
are trying to return to work before their 30 minutes are up.
