Hi,

how can execute addGroup and deleteGroup button trigger from code line in a group repeated contest ?

This is the part that add the button '+':

<a class="addGroup" href="#"><?php echo FabrikHelperHTML::image('add.png', 'form', $this->tmpl, array('class' => 'fabrikTip', 'title' => JText::_('COM_FABRIK_ADD_GROUP')));?></a>

and '-':

<a class="deleteGroup" href="#"><?php echo FabrikHelperHTML::image('del.png', 'form', $this->tmpl, array('class' => 'fabrikTip', 'title' => JText::_('COM_FABRIK_DELETE_GROUP')));?></a>

Anyone can help me ?

Thx
