we are designing our web site and received the authorisation for electronic payments.

to execute the payment a MD5 hash value has to be generated by the concatenation of all data/parameters (filled in the rsform) and a merchant password.

in the bank manual and samples there is an application form with several <input type=hidden...> containing info about merchant and passwords and so on.

then the following:

<input id='CheckSumHeader' name='CheckSumHeader' value='18AmountToPay,PayToMerchant,MerchantName,AmountCurrency,Details1,Details2,PaymentOKURL,PaymentFailURL,FirstName,LastName,Address,City,Zip,Country,Telephone,Email,OriginalAmount,OriginalCurrency,000000000000000000000000000000000000000000000000' type='hidden' />

built using other fields

and the form action is:

<form action='https://www.electronicpayment/client/Page/default.aspx?xml_id=/uk-UK/.loginToPay/' method='post'>

basically the probelm is this: when i click on [submit] is it possible to send data to the above mentioned address leaving same data also stoed in our rsform database?

Thanks for your attention
