Transparency in an animation

I'm not sure if this is advanced or begginer help that I need, but as it is my first post in this forum I'll do it here... :D
I have a probleme with making the background of an animated gif transparant...
I first made this animation:

Then I deleted (using magical wand on the black and pressing delete ;) ) the background in ImageReady 7.0 and I got this image:

Which is not realy what I want. Btw, I did "save optimized". Does some1 knows how I can edit it so I only have 1 ring and it is transparant?

Grtz, Doody!

If the Rings are on different layers: On every frame hide all layers you don't want to see. You have to hide the layers which you don't want to see on every frame.

Because I forgot to save the original version of the first animation (or failed doing that are something) I had to use the gif u all see above to make the 2nd animation. So the ring was not in a different layer. When this would have been the probleme it would already have been the case in the first animation... Btw, when I just press play in ImageReady it does show right. It only gives problems when I preview in IE or after I saved (like the one above or when I look at it in "My pictures").

Well thx I guess :D : I started all over and I don't have the probleme anymore...But I have another probleme (but it's less dramatic :D ).

As u can see lots of rings have been "damaged"... How can I avoid that?
