Drop Down List to Use Item Messed Up

[Abronsyth]

It's driving me nuts, haha XD ((Took my 6 months to learn html and css, taken me 3+ years and still haven't learned php...someday I'll be able to solve these issues. Soooome day.)).

Inventoryview.php:

PHP Code:

    public function uses(){
        $mysidia = Registry::get("mysidia");
        $document = $this->document;    
        if($mysidia->input->post("aid")){
            $message = (string)$this->getField("message");
            $document->setTitle($mysidia->lang->global_action_complete);
            $document->addLangvar($message);
            return;        
        }
        
        $petMap = $this->getField("petMap");
        $document->setTitle($mysidia->lang->select_title);
        $document->addLangvar($mysidia->lang->select);        
        $chooseFrom = new Form("chooseform", "uses", "post");
        
        $adoptable = new DropdownList("aid");
        $adoptable->add(new Option("None Selected", "none"));
        if($petMap->size() > 0){
            $iterator = $petMap->iterator();
            while($iterator->hasNext()){
                $adopt = $iterator->nextEntry();
                $adoptable->add(new Option($adopt->getValue(), $adopt->getKey()));
            }
        }        
        $chooseFrom->add($adoptable);
        
        $chooseFrom->add(new PasswordField("hidden", "itemname", $mysidia->input->post("itemname")));
        $chooseFrom->add(new PasswordField("hidden", "validation", "valid"));
        $chooseFrom->add(new Button("Choose this Adopt", "submit", "submit"));
        $document->add($chooseFrom);
    } 


Inventory.php:

PHP Code:

    public function uses(){
        $mysidia = Registry::get("mysidia");
        $document = $mysidia->frame->getDocument();
        $item = new PrivateItem($mysidia->input->post("itemname"), $mysidia->user->username);   
        if($item->iid == 0) throw new ItemException("use_none");
        
        if($mysidia->input->post("aid")){
            if(!$item->checktarget($mysidia->input->post("aid")) or $mysidia->input->post("validation") != "valid"){
                throw new ItemException("use_fail");
            }
            elseif(!$item->randomchance()){
                $item->remove();
                throw new ItemException("use_effect");
            }
            else{ 
                $message = $item->apply($mysidia->input->post("aid")); 
                $this->setField("message", $message);
            }    
            return;            
        }

        $stmt = $mysidia->db->select("owned_adoptables", array("aid", "name"), "owner = '{$mysidia->user->username}'");
        $map = $mysidia->db->fetchMap($stmt);
        $this->setField("petMap", $map);
    }
