Problem with payment Module

[alexipr]

i am creating a payment module for zen cart but for some reason i cant see the payment module on the administration panel after i upload it to the server, i think is something wrong with the code, can somebody take a look at it and help me out thanks! ..

<?php

  class paytech {
    var $code, $title, $description, $enabled;


    function https_send($params)

Problem is probably in the admin mode section, i suggest to remove the configuration parameters one by one to pinpoint where the problem comes from, also maybe empty the check function too to see if the error comes from there. Maybe not that important but why all the sort order parameters are the same?
