No errors, just a blank page?

[FounderSim]

So my tester/explore page works then but when I add the method investigate, I can't even access the tester/explore page. Its just blank. I have checked and rechecked both the controller and view for sytanx errors and can't seem to find any. I noticed sometimes if I will not be alerted of any error if I dont pass two variables to certain functions in mysidia so I checked all them as well because that usually results in a blank page as well.

The Controller:

	public function investigate(){
		$mysidia = Registry::get("mysidia"); 
		
		$explore_var = $mysidia->session->fetch("explorer");
		
		if($explore_var == 0)
		{
			$this->setField("explorer", new String("Stupid Hacker..."));
		}
		else
		{
			$mysidia->session->assign("explorer_step", 2);
			$stmt = $mysidia->db->select("explorer", array("eType"), "eid={$explore_var}");	
			$result = $stmt->fetchObject();

			if($result->eType == "item")
			{
				$this->setField("explorer", new String($result->eType));
			}
			elseif($result->eType == "coin")
			{
				$this->setField("explorer", new String($result->eType)));
			}
			elseif($result->eType == "pet")
			{
				$this->setField("explorer", new String($result->eType));
			}
			else
			{
				$this->setField("explorer", new String("boo"));
			}
		}
	}

The View

	public function investigate(){
		$mysidia = Registry::get("mysidia");
		$document = $this->document;  
		
		
        $document->setTitle("TEST");
		
		
		$emessages = $this->getField("explorer");
		
		
		switch($emessages)
		{
//manual edit of comments during paist of this code =)
			case "item":
				$document->add(new Comment('Ooh/a>'));
				break;
			case "pet":
				$document->add(new Comment('oh/a>'));
				break;
			case "coin":
				$document->add(new Comment('Ooh">Continue</a>'));
				break;
			default:
				$document->add(new Comment($emessages));			
		}
	}
