Error payment

[brushrivera2012]

Hello everyone, I have a problem, in payments I always get error when I have the following code

  <input type="hidden" name="button" value="buynow">
                            <input type="hidden" name="amount" value="" id="amountpaypal">  
                            <input type="hidden" name="item_name" value="Recarga">
                            <input type="hidden" name="item_number" value="recarga-rank">
                            <input type="hidden" name="currency_code" value="USD">
                            <input type="hidden" name="lc" value="ES">
                            <input type="hidden" name="env" value="www.sandbox">

  <input type="hidden" name="button" value="buynow">
                            <input type="hidden" name="amount" value="" id="amountpaypal">  
                            <input type="hidden" name="item_name" value="">
                            <input type="hidden" name="item_number" value="recarga-rank">
                            <input type="hidden" name="currency_code" value="USD">
                            <input type="hidden" name="lc" value="ES">
                            <input type="hidden" name="env" value="www.sandbox">

but if I put the next one (without Recarga in value  <input type="hidden" name="item_name" value=""> ) if it works, can I leave it like this? Is there a security problem if I work that way? thank you very much

is this the complete code you are using, doesn't look to be since you're missing the form tags for example. Can you post the complete button code please?
