Applying AniMagiX-gecko-script to w3c-standard

[ecko]

First, look at

http://www.singyfamily.com/Hob/tech/aniMagiX/gecko/geckos.html

to see the gecko animation.
Then look at the script

http://www.singyfamily.com/Hob/tech/aniMagiX/aniMagiX.js

The problem there is to insert the 'if(document.getElementById)' expression to comply with the w3c standard. How do I do this? I tried to make the script running in Mozilla Gecko, but I couldn't get it.
Is there any expert who can help me?

It is useless to check for IE, document.getElementById works for mozilla and IE.
The script should check for an old netscape that works with document.layers.
Just change all document.layers[...] with
document.getElementById(...)
