Photoshop save as GIF help

[Hakkola]

Created a little animation, a pendulum that has to repeat and I'd like to save it as a gif but can't seem to figure it out, when I try saving as gif the only way I know how it wants to delete the hidden frames. I'll try with them all selected and see how that goes. It doesn't HAVE to be a gif but has to repeat.

Any suggestions?

I'm using CS5.

NVM, figured it out, save for web and devices option.
