i cannot use the variable from invoice.php in checker....can someone help me out...thank you

phpinfo() gives information about your server, not about the handheld. It is quite possible that your handheld does not support this.

You can pass the session id as a $_GET variable.
That will work even if cookies are not suported

its using windows ce...i'm not sure, but when i check the browser, it does accept cookies....
$_Get is to go get something from html forms right?...can i use to it to pas information around?

i'll take a look...thanks...willl update if i got anything

off the topic question, does using wifi affects our session or cookie, is it possible that my handheld doesn't support cookies?
