Hello all! I have a script that changes the color of a page. Problem is that the cookie does not keep the choice when you reload or go back to the page. I have tried some onLoad functions for the body tag with some code that I have tried to modify, but no luck. Is there something I am missing in my setCookie function, or do I need another function besides that? Thanks for the help! Norman.

<html>
<head>
<title>Color change cookies</title>
<script>
function setCookie()
{
var expiresDate = new Date();

expiresDate.setFullYear(expiresDate.getFullYear() + 1);
document.cookie = encodeURI("setCookie="
+ document.colorchoice.selection.value)+ "; expires = "+ expiresDate.toUTCString();

alert("Your background color has been saved for your next visit to this page");

}


function colorit() {
var Color = parseInt(document.colorchoice.selection.selectedIndex)
changeColor(Color)

}
var colorlist = new Array("red","blue","yellow")
function changeColor(color) {
document.bgColor = colorlist[color]
document.colorchoice.value = colorlist[color]
}

</script>
</head>
<body>
<form name="colorchoice">
<p> <h2>Click button to pick color.</h2>
<SELECT NAME="selection">
<OPTION>Red
<OPTION>Blue
<OPTION>Yellow
</SELECT>
<INPUT TYPE="button" NAME="Change_Color" VALUE="Change Color" onClick="colorit(); setCookie();">
</form>
</body>
</html>

<!-- TWO STEPS TO INSTALL COOKIE - FAVORITE BACKGROUND COLOR:

   1.  Paste the designated coding into the HEAD of your HTML document
   2.  Put the last script into the BODY of your HTML document  -->

<!-- STEP ONE: Copy this code into the HEAD of your HTML document  -->
       
<HEAD>

<SCRIPT LANGUAGE = "JavaScript">
<!-- Original:  Mattias Sjoberg -->

<!-- This script and many more are available free online at -->
<!-- The JavaScript Source!! http://javascript.internet.com -->

<!-- Begin
var expDays = 30;
var exp = new Date();
exp.setTime(exp.getTime() + (expDays*24*60*60*1000));
function color(){
var favColor = GetCookie('color');
if (favColor == null) {
favColor = prompt("What is your favorite background color?");
SetCookie('color', favColor, exp);
}
document.bgColor=favColor;
return favColor;
}
function set(){
favColor = prompt("What is your favorite background color?");
SetCookie ('color', favColor, exp);
}
function getCookieVal (offset) { 
var endstr = document.cookie.indexOf (";", offset); 
if (endstr == -1)   
endstr = document.cookie.length; 
return unescape(document.cookie.substring(offset, endstr));
}
function GetCookie (name) { 
var arg = name + "="; 
var alen = arg.length; 
var clen = document.cookie.length; 
var i = 0; 
while (i < clen) {   
var j = i + alen;   
if (document.cookie.substring(i, j) == arg)     
return getCookieVal (j);   
i = document.cookie.indexOf(" ", i) + 1;   
if (i == 0) break;   
} 
return null;
}
function SetCookie (name, value) { 
var argv = SetCookie.arguments; 
var argc = SetCookie.arguments.length; 
var expires = (argc > 2) ? argv[2] : null; 
var path = (argc > 3) ? argv[3] : null; 
var domain = (argc > 4) ? argv[4] : null; 
var secure = (argc > 5) ? argv[5] : false; 
document.cookie = name + "=" + escape (value) +
((expires == null) ? "" : ("; expires=" + expires.toGMTString())) +
((path == null) ? "" : ("; path=" + path)) + 
((domain == null) ? "" : ("; domain=" + domain)) +   
((secure == true) ? "; secure" : "");
}
function DeleteCookie (name) { 
var exp = new Date(); 
exp.setTime (exp.getTime() - 1); 
var cval = GetCookie (name); 
document.cookie = name + "=" + cval + "; expires=" + exp.toGMTString();
}
// End -->
</SCRIPT>

<!-- STEP TWO: Copy this code into the BODY of your HTML document  -->

<BODY>
<a href="JavaScript:set()">Change background color</a>
</textarea><br></td></tr>
</table>
</form>

Hi Telli! Thanks for the help! Is there any way though to keep my code and make the cookie stay? I need to use a button to set the cookie to remember the users choice when they return to the page. Thanks again!
