Animation Help

EDIT: I think I figured it out now. Thanks all

I checked the f.a.q. section and found a bunch of stuff on keeping your animation under 40kb but I couldn't find the answer to my question so I thought I'd ask:) I use PS7 and IR
I made an animation. It's how I want it. The size is good the framing fits. But when I preview it, it looks all weird. This is what the screen says.


Format: GIF
Dimensions: 100w x 100h
Size: 31.16K
Settings: Custom, 256 Colors, 100% Diffusion Dither, 13 frames, Transparency on, No Transparency Dither, Non-Interlaced, 0% Web Snap
The final screen (with the *squee* is supposed to be on a black bg)
I guess my question is how do I get the transparent-ness of it to go away. I've never had this problem before.

Thanks!
