Hi, I coded a web page with two set of maps. Left and right map has their own blue/red buttons which should turn from blue to red when the mouse is over them. The left set of buttons stay blue even mouse over. What's the problem? The play function(animate) doesn't work either. Why? <CODE> <HTML> <META HTTP-EQUIV="Refresh" CONTENT=300> <HEAD><TITLE>Parallel Visual Exploring</TITLE></HEAD> <SCRIPT LANGUAGE="JavaScript"> // Animator internal variables var oldidxLeft = -1; var oldidxRight = -1;
