Passing objects into methods or functions

Im trying to pass an object into functions and class methods, and for some reason, Im unable to access the object's methods. When I var_dump() the object, its a valid object with the function or class method. When I check via get_class_methods, all the methods are there, from within the function or class method. I tried passing by reference, and the regular "copied" way. I end up with the error -> Fatal error: Call to undefined function: display_thumbnails() in ...... I can access the object's variables, but not it's methods Maybe because Im tired, but if anyone experienced this before, I'd greatly appreciate any feed back on this. Thanks ---------------- class class { var $_tpl; var $gal_tpl = array(); function gallery_class(&$tpl) {

       if (is_object( $tpl ))
       {
           $this->_tpl = $tpl;
       }

} } ?>
