Screen is blank when I add call to another method in different model?

[eluser]gypmaster[/eluser]
When I click on the link to which calls the view method the following appears in my browser address bar:

http://localhost/codeIgniter/index.php/property/view/7

But the screen is completely blank.

btw, I've changed the model to use result_array() but it made no difference.

here's the view

Code:

<?php
echo '<h2>'.$property['title'].'</h2>';
echo $property['address1']."<BR>".$property['address2']."<BR>".$property['address3']."<BR>".$property['postcode']."<BR>".$property['area']."<BR>";

foreach ($rooms as $room_item)
{
  echo "<p>".$room_item['roomid']."<BR>";
}

Thanks
