mouseover javascript not working for me

I've successfully created a button that changes color when I hover and when I click it goes to a website.  Next, I want a mouseover of this same button to make another image come up and go away when the mouse leaves.  When I add the code for this, it doesn't work.  It worked fine in Action3.0.  I don't know what I'm doing, but how can I fix this code so it will work please?
