addChildAt for top layer confusion

[tanvira5454192]

				//Level 2

if (score==10 && score<30 ){

var myMovieClipbg:winbg = new winbg();

myMovieClipbg.x = 0;

myMovieClipbg.y = 5;

addChildAt(myMovieClipbg,1);

}

//level 3

else if (score>30 && score<60){

var lastmc:tired = new tired();

lastmc.x = 0;

lastmc.y = 0;

addChildAt(lastmc, 1);

}

"lastmc" should be top layer background when score is greater than 30 . but its not working . moreover if i use addChild(lastmc) . it becomes top of all layer . so My hero and enemies everything go down. i can not play . but  need lastmc just top of myMovieClipbg background layer .

i assume the confusion coming from addChildAt

note addChildAt(myMovieClipbg,1); is working fine for second level. it brings the background top of first background .

but addChildAt(lastmc, 1); is failing to bring the background of of second background

kglad sir ,

it still does not working

[kglad]

what do you see that makes you think it's not working?

[tanvira5454192]

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

yes. this error does not come if i write addChild(lastmc);

but it comes if i write your code myMovieClipbg.addChild(lastmc);

[kglad]

then either myMovieClipbg doesn't exist, or you made it local to a function or some other timeline.

yes. now its working . its my bad. i fixed the bug . and now myMovieClipbg.addChild(lastmc); working fine

thanks sir for helping
