Re: DOM and Frames

I've tried the following, but I'm getting an "x is null or not an
object" error.

<a href="javascript:top.map.focus(mv, 4)">Mountain View</a>

My understanding is top = top frame, map = the frame I have named map

Am I adding this in the wrong place? Do I need to narrow it down
further? If it's not already apparent, I'm pretty new to this.
