Gallery Help

Question

Click Here To See It
Ok well im trying to make a simple gallery in action script
3. I've done a much more simple one from a tut (link above) and
that one works fine, then i've done basically the same thing but it
doesnt work.
I check the script and it says no error but when i do Crtl
Enter i get a few error message and im not sure what they mean or
how to fix them.
1120: Access of undefined property biohazard.
biohazard.addEventListener(MouseEvent.CLICK,colornav);
And a few more like that for each picture.
The actual code is :
stop();
function colornav(event:MouseEvent):void {
gotoAndStop(event.target.name);
biohazard.addEventListener(MouseEvent.CLICK,colornav);
eagle.addEventListener(MouseEvent.CLICK,colornav);
way.addEventListener(MouseEvent.CLICK,colornav);
unkownpaper.addEventListener(MouseEvent.CLICK,colornav);
cotn.addEventListener(MouseEvent.CLICK,colornav);
unkownfront.addEventListener(MouseEvent.CLICK,colornav);
unknownback.addEventListener(MouseEvent.CLICK,colornav);
grungehead.addEventListener(MouseEvent.CLICK,colornav);
ttposter.addEventListener(MouseEvent.CLICK,colornav);
Which should work i believe.
Any help?

Ok, here is the problem.
SimpleButton has several objects for their states - so the
CLICK event is dispatched initially not from the button itself but
from the object that represents the down state. This object is the
target. The button instance is the currentTarget - parent of the
down state child inside SimpleButton.
In any case, change your code from target to currentTarget
and it works - I checked it out:
