PHP cookie strangeness

[Anon]

There is a cookie problem that I am encountering that I have battling for hours, and I have not been able to find a solution. This is the problem: I am setting a cookie on Page A, then calling it later on Page B. The first time I set the cookie on Page A, Page B tells me it is "null." However, if I go back to Page A and set it a second time, then it shows it on Page B just fine. It consistently follows this pattern. Please help!!

Here is the code that sets the cookie in PHP (only an excerpt): It is part of a form page that posts back to itself.

switch ($do) {
case "authenticate":

$value="$email" . "&" . "$pass" . "&" . "$first.$last" . "&" . "45" . "&" . "$Number";
setcookie("ubber2452172.1721", $value, "time() + (365 * 86400)", "/");
break;
}

And now the page reading it in with JS.
function getCookie(name) {
var cname = name + "=";
var dc = document.cookie;

if (dc.length > 0) {
begin = dc.indexOf(cname);
if (begin != -1) {
begin += cname.length;
end = dc.indexOf(";", begin);
if (end == -1) end = dc.length;
return (dc.substring(begin, end));
}
}
return null;
}

and the code later in the page:

var user_cookie = getCookie('ubber2452172.1721');
var user_array=user_cookie.split("&");
user_array[2] = unescape(user_array[2]);
var test_array=user_array[0].split("%26");
var name_array=test_array[2].split(".");
var name = name_array[0] + " " + name_array[1];

document.writeln('Hello, ', name)
