Restyling the adopt manage page

[kingsofjuly]

Where do I insert this, please? I attempted to place it under line 38:

public function manage(){
$this->setField("aid", new Integer($this->adopt->getAdoptID()));
$this->setField("name", new String($this->adopt->getName()));
$this->setField("image", $this->image);
}

but it keeps throwing me to a blank page, on both My Adopts and Manage the Pet page. I have altered the URLs to my own domain. Would love to implement this, as I've just added the stat adding script :) Thanks
