trouble creating animated gif in fireworks CS5

can someone explain to me why i'm unable to create an animated gif using fireworks cs5?

I tried 3 different ways to save/export the file and none worked. here's what I did: http://screencast.com/t/gRXUwsp2yshu

please advise. thanks in advance!

Looks like you did everything right. Could it be that the photo viewer doesn’t display animated GIFs as animations? Load the images in a browser of your choice and look what happens.

You're right! thank you!
