validate append help

hi
I would like the error message to be an em inside my label tag. how would i do this?

<label for "formname" class="label">Your Name:</label>
<input type="text" name="formname" class="required" id="formname" size="35"/>

and would like it so it has

<label for "formname" class="label">Your Name:<em>error message here please</em></label>
<input type="text" name="formname" class="required" id="formname" size="35"/>

been plaing around and cant append it there. cheers
