yeah but that doesn't mean you have to start replying to just me,
keep your replies on list please - it helps others, and stops me from

$pakora will only exist if you set or if register_globals
is turned on. (I get the feeling you have register_globals turned on -
not the recommended setting IMO)

> setcookie("cookie[pakora]", "$pakora Pakora");

try dumping the contents of $_COOKIE:

var_dump($_COOKIE);

I would imagine the following gives you the number you are looking for:

echo intval($_COOKIE['cookie']['pakora']);

so...

<?php

if (!isset($_COOKIE['cookie']['pakora'])) {
$pakora = 0;
} else {
$pakora = intval($_COOKIE['cookie']['pakora']);
}

if (isset($add)) {
$pakora++;
setcookie("cookie[pakora]", "$pakora Pakora");
}
