problem with animate

problem with animate

Hi,

this is my first time using jquery and I'm having problems with an animation.
Basically I have a div with a background image, and when the mouse is over the "parent" <a> the div resizes so the text behind the layer displays.

And it kinda works, but when I move the pointer over the middle of the element the animation goes "crazy", and goes up and down until mouseover.

So yeah, Im stuck on this one...

Please take a look at  http://test.lundbeckconsulting.no/ContentBox/default.html and tell me what Im doing wrong.

Thanks :)
