HTML_TreeMenu

I've been checking out the HTML_TreeMenu package and so far really like it. I had a couple questions that I was hoping someone could help me with. I have the class working in a recursive function that will create a tree menu for a directory listing creating the folders for sub directories and changing icons for file types. This is a test app for a project I want to work on. This is not the actual code but I was having an issue with trying to handle the first ->additem method. It does not want to be used within the function I have. I have subsequent ->additems calls in the same function and they work fine - it handles all the resursive directories ok. I get : Fatal error: Call to a member function on a non-object It would appear to be an issue with address pointer to the class object but the calls work fine in the function for all subsequent calls just not the first ->addItem, To simulate the error I have the following extract. Since I need to pass $nodel to the function which picks it up as an address - function showfoldertree(&$treeclass,$rootdir,$files,$baseurl) { Why would this snippet of logic not work Assign $test to the address and then instead of $foo = &$nodel->addItem(new ... use $foo = $test->addItem(new ... $menu = new HTML_TreeMenu(); $node1 = new HTML_TreeNode(array('text' => $rootdir ,'link' => $baseurl ,'icon' => $folder_icon)); $test = &$nodel; $foo = $test->addItem(new HTML_TreeNode(array('text' => $subdir,'link' => $baseurl.$subdir,'icon' => $folder_icon))); showfoldertree($foo,$rootdir,$filelisting,$baseurl); Any help would be appreciated Blaine
