Once again, $pagename is not automatically in the scope of the callback  
function. If you want to use $pagename in the callback, it must somehow get  
into that callback. If it does, yes, when defining the callback, use  

One way is to pass the value of $pagename to a temporary global variable and  
get it inside the callback PHP code.

variable to all callback functions that use it.
