Are repeating fieldsets inside tables known not to work? They definitely aren't working for me on the dev server. Example: <table> <thead> <tr><th>Item</th><th>Notes</th></tr> </thead> <tbody> <fieldset class="repeating_tomes"> <tr> <td><input type="text" name="attr_tome_name" /></td> <td><input type="text" name="attr_tome_notes" /></td> </tr> </fieldset> </tbody> </table>
