Hi,
In my controller

     function designpage() 
    {
       //to create a form Untitled
 $this->Form->saveField('name','Untitled Form');
     echo $this->Form->getLastInsertId();//here it works

    }

        function insertformname()
      { 

          echo $this->Form->getLastInsertId(); //this doesnt echo at all



      }

Please suggest me..
