Problem to set a cookie

Hi!

I validate a user and set a cookie woht the following sentence:

setcookie("usNick",$nickN,time()+7776000);
setcookie("usPass",$passN,time()+7776000);

then I want to validate if the cookie is set with the following
sentence and it seems to enter in the "else", so the cookie was not
established.

if(isset($HTTP_COOKIE_VARS["usNick"]) &&
isset($HTTP_COOKIE_VARS["usPass"]))
{
$result = mysql_query("SELECT * FROM usuarios WHERE nick='".
$HTTP_COOKIE_VARS["usNick"]."' AND password='".
$HTTP_COOKIE_VARS["usPass"]."'");
}
else
{
setcookie("usNick","x",time()-3600);
setcookie("usPass","x",time()-3600);
}

Can anyone help me with this? I mena, setting the cookie correctly

Regards,

Ezequiel
