I am trying to use paypal as my payment provider with the tea commerce cart but when i click payment to go to the paypal page after agreeing to to the the order I get taken to a paypal page but get the error Your shopping cart is empty even tho there is items in by tea commerce cart.

I have the following settings in the tea commerce section

Paypal account email - the email from my paypal sandbox account

Language - UK

Continue URL - /Basket/Confirmation

Cancel URL - /Basket

Payment action - sale

API username - the username from my paypal sandbox account

Product number property alias - productCode

Productname property alias - productTitle

Shipping method format string - shipping fee ({0})

payment method format string Payment fee ({0})

On my accept order form I call the paypal method with

<form action="/Basket/Payment" method="post">
       <input id="acceptOrderSubmit" type="submit" value="Payment"/>
    </form> 

my jquery method is

jQuery('#acceptOrderSubmit').live("click", function () {
  //We check if the terms has been acceptet
  var jQEle = jQuery('#acceptTermsCheck');
  if (!jQEle.is(':checked')) {
    alert(jQEle.attr('alt'));
  } else {
    TeaCommerce.goToPayment();
  }
  return false;
});

What have i missed do I need to pass more data to paypal
