actionscript 3 - Dang Error #1009 ! -

I am creating a simple flash site for a friend, whose spa is.

This error:

  Error # 1009: Null object can not use context or method of reference. Through the process of commenting on the code, I have narrowed down my link section:  
  vox_link   
 
 addEventListener (MouseEvent .CLICK, gotoVox); Function gotoVox (evtObj: Event): Zero {var vox site: URLRequest = New URLRequest ("http://www.voxmundiproject.com"); NavigateToURL (voxSite, "_blank"); }  

Commented with this section, I did not get 1009 errors When the code is activated, I get an error.

My code syntax is correct, so I've been stumped.

Does anyone know what is wrong with me?

Thank you

The error says that you are using something / Properties) that is empty. What I see is probably vox_link which is taped here or does not exist.
