Your totorial located here [http://www.kirupa.com/developer/flash8/centered\_popup\_window.htm](http://www.kirupa.com/developer/flash8/centered_popup_window.htm)  
is given me trouble.

Ive spent about an hour with it and keep getting syntax errors. Seem Flash CS3 doesnt like the code…

btn\_Up.onRelease = function() {  
getURL(“javascript:Launch(‘[http://www.kirupa.com/sotw/archive.htm](http://www.kirupa.com/sotw/archive.htm)’, 400, 300)”);  
};

Every time i run the movie i get a syntax error.  
1120: Access of undefined property btn\_Up.  
1180: Call to a possibly undefined method getURL.

Whats the problem?
