Fatal error: Call to a member function getGUID()

Hi there.  I am new to elgg, and when I click on the menu item GROUPS a blank screen appears with the following text

Fatal error: Call to a member function getGUID() on a non-object in /home/content/25/7452025/html/indiehorror/mod/groups/views/default/forms/groups/search.php on line 17

Is there something I need to add/change in the search.php file?
