GroceryCrud Table Relationships set_model (join tables) [EDITED]

I have two tables like this:

CREATE TABLE `tblFacilityHrs` (
          `id` int(11) NOT NULL AUTO_INCREMENT,
          `uid` varchar(45) DEFAULT NULL,
          `title` varchar(100) DEFAULT NULL,
          `description` text,
          PRIMARY KEY (`id`),
          KEY `key_uid` (`uid`)
        ) ENGINE=InnoDB AUTO_INCREMENT=9 DEFAULT CHARSET=latin1$$

        CREATE TABLE `tblFacilityHrsDateTimes` (
          `id` int(11) NOT NULL AUTO_INCREMENT,
          `owner_uid` varchar(45) DEFAULT NULL,
          `startDate` date DEFAULT NULL,
          `endDate` date DEFAULT NULL,
          `startTime` time DEFAULT NULL,
          `endTime` time DEFAULT NULL,
          `days` int(2),
          `recurrence` int(1) DEFAULT NULL,
          PRIMARY KEY (`id`),
          KEY `fk_fh_owneruid` (`owner_uid`),
          CONSTRAINT `fk_fh_owneruid` FOREIGN KEY (`owner_uid`) REFERENCES `tblFacilityHrs` (`uid`) ON DELETE CASCADE ON UPDATE CASCADE
        ) ENGINE=InnoDB AUTO_INCREMENT=52 DEFAULT CHARSET=latin1$$

In my controllers folder I have a file named main.php with the following code:

...
function fitnessSchedule()
    {
        $this->config->set_item('url_suffix', '');
        $crud = new grocery_CRUD();

        $crud->set_model('schedule_model');
        $crud->set_table('tblFitnessClasses');
        $crud->join_table('tblFitnessClasses','tblFitnessClassDateTimes');
        $crud->columns('title','description','location','startDate','endDate','startTime', 'endTime', 'days', 'recurrance');
        $crud->display_as('title','Event')
             ->display_as('description','Description')
             ->display_as('location','Location')
             ->display_as('startDate','Start Date')
             ->display_as('endDate','End Date')
             ->display_as('startTime','Start Time')
             ->display_as('endTime','End Time');
        $crud->required_fields('title','location');
        $crud->set_subject('Event');              

        $output = $crud->render();
        $this->_example_output($output);    
    }

    function _example_output($output = null)    
    {
        $this->load->view('main_view', $output);    
    }
...

In my models folder I have this:

<?php
class schedule_model extends grocery_CRUD_Model
{
        function join_table($table1, $table2)
        {
         if($this->$table1 === null)
          return false;

         $select = "{$this->$table1}.*";
         $select .=",$table2.startDate, $table2.endDate, $table2.startTime, $table2.endTime, $table2.days, $table2.recurrence";

         if(!empty($this->relation))
          foreach($this->relation as $relation)
          {
           list($field_name , $related_table , $related_field_title) = $relation;
           $unique_join_name = $this->_unique_join_name($field_name);
           $unique_field_name = $this->_unique_field_name($field_name);

        if(strstr($related_field_title,'{'))
                $select .= ", CONCAT('".str_replace(array('{','}'),array("',COALESCE({$unique_join_name}.",", ''),'"),str_replace("'","\\'",$related_field_title))."') as $unique_field_name";
           else   
                $select .= ", $unique_join_name.$related_field_title as $unique_field_name";

           if($this->field_exists($related_field_title))
                $select .= ", {$this->$table1}.$related_field_title as '{$this->$table1}.$related_field_title'";
          }

         $this->db->select($select, false);


         $this->db->join('uid', '$table2.owner_uid = $table1.uid');

         $results = $this->db->get($this->$table1)->result();

         return $results;
        }

        /* function join_table($table1, $table2)
        {
                $this->db->select('$table1.*');
                $this->db->join('$table2','$table1.uid = $table2.owner_uid','left');
                $this->db->get('$table1');
         }*/
}
?>

I'm getting this error:

Fatal error: Call to undefined method grocery_CRUD::join_table() in C:\xampp\htdocs\codeigniter\application\controllers\main.php on line 234

I'm basically trying to concatenate tblFacilityHrs with tblFacilityHrsDateTimes by way of UID (uid to owner_uid). I want to display both tables at once so that when a user edits the table not only do they edit the event's name/location they also edit its time/date etc.
