Hello I’m new to AS3 and looking for some help on an assignment!! Put simply on a website I am developing I can access the “teams” & “bikes” pages because they are part of the main nav. However the “yamhome” is part of a subnav off of the “teams” page. Flash output is throwing me an error I listed below. Code is below that!

Anyone have any suggestions, I’m just starting out with AS3, thanks!

**error:** TypeError: Error #1009: Cannot access a property or method of a null object reference.

**code:**

home\_btn . addEventListener(MouseEvent.CLICK, homePage);  
teams\_btn . addEventListener(MouseEvent.CLICK, teamsPage);  
bikes\_btn . addEventListener(MouseEvent.CLICK, bikesPage);  
yamhome\_btn . addEventListener(MouseEvent.CLICK, yamHomePage);

function homePage(event:MouseEvent):void  
{  
gotoAndStop(“home”);  
}

function teamsPage(event:MouseEvent):void  
{  
gotoAndStop(“teams”);  
}

function bikesPage(event:MouseEvent):void  
{  
gotoAndStop(“bikes”);  
}

function yamHomePage(event:MouseEvent):void  
{  
gotoAndStop(“yamhome”);  
}
