payment through ccbill

Hi, i would like to offer a payment provider to upgrade membership levels. what ive already done: 1.) site is running in free mode: unchecked 2.) definated a membership levels (master) with all rights, price in $ and for 1 momth 3.) payment not recurring 4.) downgrated the "normal" user level to make it more interesting in getting the full acess 5.) Number of days before membership expiration to notify members: -1 6.) Notify members about membership expiration only once: checked 7.) Enable promotional membership: unchecked 8.) Currency sign: $ 9.)currency code: US Dollar 10.) Enable recurring billings: Unchecked 11.)ccbill activity: checked 12.) mode. live 13.) ordered a ccbill account, got it 14.) insered the 6 digit Account number 9xxxxx at the backend of dolphin 15.) setup a subaccount at ccbill 16.) insered the 4 digit subacount number 0xxx at the backend of dolphin 17.)defined approval url (http://www.website.com/member.php) 18.) defined home url (http://www.website.com) 19.)defined denial and tour url (does not exist, therefore:) (http://www.website.com) 20.)defined approval post url (http://www.website.com/checkout/ccbill.php) 21.) defined denial post url (http://www.website.com/checkout/ccbill.php) 22.) went through the pricing admin and defined the price seen on #2 23.)went through the form admin, defined a form 24.) insered the 5 digit form id ( incl. cc at the end) into the backend 25.) went through "create html" 26.) insered the value taken form "create html" into ssid and allowed tipes (the ssid from "create html" is longer then the ssid seen at the form admin, but i already tried both of them when i set up a new user at my public site and try to upgrade, there appairs a error message at the checkout.php: "recurring not allowed" . but i dit not checked that box at the backend, at ccbill the price is also not recurring. So i made a new price,in this try recurring, insered the new ssid, checked the button "recurring" at the backed of dolphin, and then cames up the error message: "recurring not supported". So i delerted the new recurring price, switched back into "not recurring" modus at the backend of dolphin, changed the value at the payment providers, but i still cant get any forthier. The loop can be found at the checkout.php between line 351 and 383. but i have no idea how to fix it. I searched the internet and all dolphin and ccbill relevant pots, without any solution. Can anybode give me a hand to fix this? regarding those very few points i have to keep in mind at the backend of dolphin, i guess that the problem might be located at ccbill. But of course they do not support 3th party software problems. Therefore: if anybody can give me a hint or take a short look at my forms, i would be very greatful. kind regards,
