You can't have a form tag inside another form. The following HTML is invalid:

 <form>
   <fieldset>
     <form>
       <input>
     </form>
   </fieldset>
 </form>

The browser will silently ignore the second form, and instead will interpret your page as:

 <form>
   <fieldset>
     <input>
   </fieldset>
 </form>
