[support] Problem getting a custom menu to display (D7)

I have written a menu using a custom module. I can't get it to display on my test site. I used the menu example in the examples module as a guideline. My code can be seen at http://pastebin.com/VJiC5anM I've enabled the module and I know it's being executed, since I see the output of the dpm($items) call. I clear the cache every time I make a change to the code. Any help would be appreciated. Thanks in advance. Ken
