Transparency in an animation

I'm sorry that I alreasy posted this in "new to photoshop help" and it's not even realy about photoshop (ImageReady), but I'm just hoping for some help...

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" and it only shows this bug while opening it in something else then Imageready... Does some1 knows how I can edit it so I only have 1 ring and it is transparant?

Grtz, Doody!

I think u got quite useful answer in ur last topic. try bumping theold one instead of making a new thread.
