Nette – jednoduché vyhľadávanie v MySQL

Čaute snažím sa napísať nejaké jednoduché vyhľadávanie v NETTE, s tým ze SQL kontroluje či je nejaké pole NULL.

vyzera to nejako takto:

Presenter:

	protected function createComponentSearchForm()
	{
		$form = new Nette\Application\UI\Form;
		$form->addText('firstname', 'FirstName:')
			->setRequired('Please enter your firstname.');

		$form->addText('surname', 'Surname:')
			->setRequired('Please enter your surname.');

		$form->addSubmit('send', 'Search');

		// call method signInFormSucceeded() on success
		$form->onSuccess[] = array($this, 'searchFormSucceeded');
		return $form;
	}

	public function searchFormSucceeded($form, $values)
	{
		$this->template->searchResult = $this->search->findResults($values);
	}

model:

	function findResults($userParams)
	{
		return $this->db->query
		("
		SELECT *
		FROM candidates as c
		WHERE (@firstname IS NULL OR c.firstname LIKE '%' + @firstname + '%')
		AND (@surname IS NULL OR c.surname LIKE '%' + @firstname + '%')
		");
	}

Formulár + dump premennej:

 {form searchForm}
                                    <div class="form-group">
                                        <label class="col-md-3 col-xs-12 control-label">Meno</label>

                                        </div>
                                    </div>

                                    <div class="form-group">

                                        <div class="col-md-6 col-xs-12">
                                            <div class="input-group">

                                            </div>
                                            <span class="help-block">Hľadá priezvisko </span>
                                        </div>
                                    </div>
                                <div class="panel-footer">

                                {/form}

{dump $searchResult}

Napriek všetkemu dostavam chybu

ERROR:

Undefined variable: searchResult

Neviem sa odtiaľto odpichnúť, vedel by mi niekto poradiť?
