Trying to move mc along _y axis, help

Hello Kirupa!

I’m trying to move a movie clip along a _y axis in response to an on (rollOver) event, similarily to how the animation is built along the _x axis in this tutorial:

I’ve tried to figure this out, I’ve tried changing the code in this example, replacing the _x with _y. I guessed this would do it, but I’m missing something, and can’t get this to work.

Any advice? Kindly appreciated!
