Hi Gurus,

Please help me with this problem.

I am not able to attach my FLA file becoz of its size… which is 512kb.

Below is the code for my

// [http://code.google.com/p/tweener/](http://code.google.com/p/tweener/)

“Products”, “Services”,  
“Testimonials”, “Latest News”, “Contact”);

var total:Number = menu\_label.length;  
var i:Number = 0;  
var page:Number;  
var main\_menu:MovieClip = new MovieClip();  
stage.addChild(main\_menu);

fm\_button.visible = false;  
stop();

for (i = 0; i \< total; i++)  
{  
var btn = new flashmo\_button();  
btn.name = “btn” + i;  
btn.x = fm\_button.x;  
btn.y = fm\_button.y + 200 + i \* ( fm\_button.height + 20 );  
btn.alpha = 0;  
btn.buttonMode = true;  
btn.item\_no = i;  
btn.flashmo\_click\_area.addEventListener( Event.ENTER\_FRAME, btn\_enter );

```
var each_substring:Array = menu_label*.split("|");
btn.flashmo_button_label.fm_label.text = each_substring[0];
btn.item_url = each_substring[1];
main_menu.addChild(btn);

Tweener.addTween( btn, { y: fm_button.y + i * ( fm_button.height + 20 ), 
				 alpha: 1, time: 0.6, delay: 0.2 * i, transition: "easeOutQuart",

import caurina.transitions.Tweener;

var tween\_duration:Number = 0.6;  
var tween\_effect:String = “easeInOutQuart”;  
var new\_x:Number;

box.mask = box\_mask;

function make\_transition(): void

else  
new\_x = box.x - box.item\_list.width;

Tweener.addTween( box, { x: new_x, time: tween_duration, transition: tween_effect } );

```

}

function create(xml\_file:String):void  
{  
box.item\_list.load\_items(xml\_file);  
box.item\_content.load\_css();  
}

flashmo\_page\_1.load\_xml(“flashmo\_219\_page\_1.xml”);//frame 11 menu Item 1  
flashmo\_page\_2.load\_xml(“flashmo\_219\_page\_2.xml”);//frame 12 menu Item 2  
flashmo\_page\_3.load\_xml(“flashmo\_219\_page\_3.xml”);//frame 13 menu Item 3  
flashmo\_page\_4.load\_xml(“flashmo\_219\_page\_4.xml”);//frame 14 menu Item 4  
flashmo\_page\_5.load\_xml(“flashmo\_219\_page\_5.xml”);//frame 15 menu Item 5  
flashmo\_list\_6.create(“flashmo\_228\_news\_list.xml”);//frame 16 menu Item 6

The above code is working fine if i use the pages as above… but i want the second menu item to display list item so i gave for frame 12 as flashmo\_list\_6.create(“flashmo\_228\_news\_list.xml”);

but it is throwing the below error

TypeError: Error #1009: Cannot access a property or method of a null object reference.  
at sample\_fla::allpages\_16/sample\_fla::frame12()[sample\_fla.allpages\_16::frame12:1]

Please help me in resolving this…
