paypal form not sending data properly - php

Question

I am trying to submit the following paypal form through a hosted-payment system. however, it does not seem to be passing through any of the variables apart from the price.
Can anyone see where I am going wrong:
<form action='https://securepayments.paypal.com/cgi-bin/acquiringweb' method='post' target='hss_iframe' id='PayPalForm' name='PayPalForm'>
<input type='hidden' name='cmd' value='_hosted-payment' />
<input type='hidden' name='charset' value='utf-8' />
<input type='hidden' name='currency_code' value='GBP' />
<input type='hidden' name='business' value='seller#email.com' />
<input type='hidden' name='paymentaction' value='sale' />
<input type='hidden' name='template' value='TemplateD' />
<input type='hidden' name='return' value='http://yoursite.com/groupon-success.php' />
<input type='hidden' name='notify_url' value='http://yoursite.com/paypal-groupon- ipn.php' />
<input type='hidden' name='item_name' value='Item name' />
<input type='hidden' name='item_number' value='4' />
<input type='hidden' name='subtotal' value='0.01' />
<input type='hidden' name='custom' value='41' />
<input type='hidden' name='address_override' value='true' />
<input type='hidden' name='first_name' value='Jack' />
<input type='hidden' name='last_name' value='Jones' />
<input type='hidden' name='address1' value='address1' />
<input type='hidden' name='city' value='Manchester' />
<input type='hidden' name='zip' value='M20 1AA' />
<input type='hidden' name='country' value='UK' />
<input type='hidden' name='billing_first_name' value='Jack' />
<input type='hidden' name='billing_last_name' value='Jones' />
<input type='hidden' name='billing_address1' value='address1' />
<input type='hidden' name='billing_city' value='Manchester' />
<input type='hidden' name='billing_zip' value='M20 1AA' />
<input type='hidden' name='billing_country' value='UK' />
</form>
it is then been passed to an iframe which seems to work fine using:
<iframe width="100%" scrolling="no" height="580px" frameborder="no" name="hss_iframe" style="float:right;"></iframe>
<script type="text/javascript">
$(function(){
$("#PayPalForm").submit();
});
</script>
Can anyone help with why this data does not seem to pass anything through
--------------- EDIT
Changed cmd to _xclick and passes through fine, so obviously an issue with _hosted-payment
Can anyone give any ideas

If by "however, it does not seem to be passing through any of the variables", you mean it doesn't display the item name / item number: that's correct. Website Payments Pro Hosted Solution doesn't currently support item details. You should remove these parameters as they're not in use for this product.
In addition, the billing/shipping address will be used, but you won't be able to modify them if you're using templateD.
