  $loginregister = false;
  	 jQuery(".btn_select").stop().animate({marginLeft: '0px' });            

 jQuery(".btn_select").click(function(){
	jQuery(this).blur();
			if ($loginregister == false){
		 jQuery(this).stop().animate({marginLeft: '70px' });
		 jQuery(window.location).attr({
                                              href: '/wp-login.php',
                                        'class': 'simplemodal-login'
                                                });
		 $loginregister = true;
			                         }else{
 jQuery(this).stop().animate({marginLeft: '0px' });
				$loginregister = false;
			                          }
			         return false;
		                });
  });
