POST script problem

[zoobie]

I'm POSTing to a http page via the script below. However, I'm unsure about the things I've put in bold. All I want to do is have the user at Paypal with the form posted data.

<?php

                   require("c_http.class");
                   $oHttp = new c_http("cmd=_xclick&business=me[b]@[/b]softhome.net&item_name=SoundWav&amount=1.95&no_shipping=1&cancel_return=http://members.lycos.co.uk/zoobie/finish.php&no_note=1","www.paypal.com/cgi-bin/webscr","[b]response.phtml[/b]");
                   if(!$oHttp->post()) {
                      echo "error";
                   }
                   echo $oHttp->RESPONSE;

?>

Directions:

first arg is the query string you want to post. it must be urlencoded. if you want the current querystring
you can use $QUERY_STRING. the second arg is the domain and the third is the file (or script) that is
getting posted to <==???
