I have a date picker and some simple validation set up here (http://www.vzapper.com/Medical-Journal/form1.php). I can’t for the life of me figure out why it’s failing in IE. The form submits without validating. Can you see what’s wrong?

Essentially, you need to make use of the form element’s “onsubmit” attribute, call a JS function for validation, and have the function return true or false. True will submit the form to the server, false will not.
