Help with custom HTML_QuickForm Renderer

Hi, I have a php file that is a custom renderer for HTML_QuickForm (it's a new smarty renderer, better then the one that comes with quickform by default.) How do I use it? I dropped the file into the Render folder inside the quickform folder. However, when I just call: $renderer = &new HTML_QuickForm_Renderer_SmartyDynamic($tpl); It doesn't work. How do I get it to recognize the new renderer class? I attached some sample code. Thanks!
