Question concerning onMouseOver

I’m having trouble with the 2nd swap statement, within the onMouseOver handler, changing the image back to its orginal image. Here is the code that i’m using in the . If someone could tell me what i’m doing wrong that would be great.

Looks like it’s missing some javascript source for the “swap” function…?

Just a thought, but using CSS and the "this.className=“stylename” for onMouseOver and onMouseOut clauses always seemed simpler to me.
