Problem with hover captions

Hi there,

I have been trying and trying to get hover captions to work on my movie. I have half a face and half a skull which will be on the first page of a website I am doing for a friend. If you click on the skull side then it links to the dark side of the site, and if you click on the face side the it links to the lighter side of the site.
But… I want hover captions to tell you that one side is dark and the other is light. Each time I try this, I follow the tutorial to a tee but the final movie doesn’t work. It comes up with (instead of a pointing finger when you are on top of the button) the insert text symbol…
Can anyone help?
click here to see (but there are no hover captions :angry: )
thank you so much in advance.
