Javascript's Journal

Ok I found a new change colors tool that works. It has the cookie and everything. I saved the cookie on three areas of my site: The change colors page, nav bar page, main page, and the site's frame (code above frame). Even though the cookie saves in the change colors page where the tool is, it does not switch over to the color I chose to the other sections. Can someone correct my mistake? Code in a textarea due to length.

<head>
<SCRIPT LANGUAGE = "JavaScript">

</SCRIPT>
</head>

function change() 
{ 
document.bgColor=document.list.colors.options[document.list.colors.selectedIndex].value; 
}
</script> 
<body bgColor="#000000" text="#ffffff" link="#ffffff" alink="#ffffff" vlink="#ffffff">
<SCRIPT>
document.write('your favorite background color is : ' + color());
</SCRIPT>
