Hello:
I have a form with a begin date and end date and I want to make sure the begin date comes before the end date. Something like the following:
<validator type="expression">
<param name="expression">begin_date < end_date</param>
<message>The begin date must precede the end date</message>
</validator>
But I don't know the syntax. How would this be done?
Thanks
Eric
