[jQuery] Validation plugin noob

[Josh Nathanson]

Hey all,
Using Jorn's Validation plugin, it's not displaying the error message.  I 
must be missing something obvious.  I'm just trying a test - it seems like 
when I submit, if the field is empty, it should display an error message 
after the input field.  What am I doing wrong?

JS:
$("#editform").validate({
 rules: {
   FirstName : "required"
   },
 messages: {
   FirstName : "Please enter your first name."
   },
 debug: true
});

Markup:
<input type="Text" size="30" name="FirstName" id="FirstName" value="" 
class="formfield" maxlength="50">
