Hieratic Category Query

[eluser]lightnb[/eluser]
I might be getting closer...

I'm now getting:

An Error Was Encountered

Error Number: 1064

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1

UPDATE Forums_Categories SET LeftID = LeftID + 2 WHERE LeftID >=

and using this code in the controller:

Code:

$this->load->model('Nested_sets_model', 'cats');
$this->cats->setControlParams('Forums_Categories', 'LeftID', 'RightID');      
              
$parentNode = $this->cats->getNodeFromId($this->validation->ParentCat);
        
$fields_array = array("categoryname"=>$this->validation->NewCatName);
$this->cats->appendNewChild($parentNode,$fields_array);

It looks like the query isn't getting finished?
