AS3 loading image from Array into empty movieclip

programming flash

I’m converting Kirupa tutorial for AS2/XML gallery to a AS3 image gallery that works with AMFPHP.

I’m running into a output error:TypeError: Error #1010

After some searching I found out that the script says that there’s a undefined propperty in the script below.

It should load an image from the Array “Image” in a empty movieclip wich excists on stage called “picture”

[COLOR=#ff0000][“picture”+0] is also used in other parts but then as [“picture”+p].[/COLOR]
[COLOR=#ff0000]P=0 with an increment based on button clicks (previous and next)[/COLOR]

          function firstImage() { 
          if (this.loaded == this.filesize) { 
          picture.alpha = 0; 
          var loader:Loader = new Loader();
          [COLOR=red]**this["picture"+0].addChild(loader);

**[/COLOR] loader.load(new URLRequest(image[p]));;
desc_txt.text = description[0];
beschrijf_txt.text = beschrijf[0];
picture_num();
}
}
