[jQuery] validate

Hello all,

I am using the JQuery validator from http://bassistance.de/jquery-plugins/jquery-plugin-validation/
. And I am using the calandar component from YUI.

The problem is similar to what bobbykjack has .

I have an input field ,when user clicks into it the calendar pops up.
When user chooses a date it fills the input box. But the error message
which had been displayed on clicking the submit button before the
field was filled does not go away.

How do I get rid off it?.

Thanks in advance .
