Animating movement with actionscript

I’m looking to be able to control the movement of a movie clip with acitonscript, specifically when i click a button, i would like my movieclip to *slide, *not jump, to a specific location. I am currently using cs3, but AS 2.0. And if i could add easing, that would be even better.

So far, all I’m able to make it do is jump to that specified location. It looks bad.

Any ideas? Or at least point me in the right direction?

Thanks,
Jen
