Use Jerry's JavaScript suggestion. Validating a field(s) that has been bound to a content source can be tricky. You must address each form element by its elements number. So each validation line will resemble :

if (document.FORMNAME.elements[X].value =="") [then do something];

...where FORMNAME is the name of the form and X is the element number.

To see a list of elements, click the Objects tab in the Inspector when you have a JavaScript window open. Then expand:: document-->FORMNAME-->elements.

Here's an example of a validation script that I use:

function validate() {
  var alertMessage = "The following required fields have been left empty:\n";
  if (document.Contact.elements[1].value == "") alertMessage += "\nTitle";
  if (alertMessage != "The following required fields have been left empty:\n") {
     alertMessage += "\n\nPlease fill out all required fields and try again.";
     alert(alertMessage);
     return false;
  } else return true;
}

Then call the function (don't use GoLive Actions) by including an onsumbit trigger in the /<form/> tag, like this: onsubmit="return validate(this)"
