Error when copying code from one file to another

Question

This bit of code works perfectly well in a test file with a single button:
var link:URLRequest=new URLRequest("http://www.mywebsite.ca");
buttonName.addEventListener(MouseEvent.CLICK, onClick);
function onClick(event:MouseEvent):void{
navigateToURL(link);
... but when I copy it into the file I'm working on, which has no other actionscripts or buttons, just a lot of animation I get this compiler error:
Description: '{' expected  Source: function onClick()event:MouseEvent):void{ 
Description: Unexpected '}' encountered   Source: {
Any ideas?

According to your error message, your onClick function declaration line closes the parenthesis twice... you may have a typo in what you actually put in the file versus what you think you put...
function onClick()event:MouseEvent):void{
