loadMovie Problem


Just want to ask if anyone in this forum can give me some idea on why my movie (SWF) is not loading,currently I have a main.swf,menu.swf and contact.swf, the main is the stage and I load menu.swf in the main.swf which works fine but when I try to load the contact.swf in the main by clicking on the menu it does not load? here the code of my button on the menu.swf


I do have a movie clip mc_container in the main.swf which will hold the contact.swf but it does not work can anybody point me to the right direction?
