Hi, Am new to RoR and am trying to use the Payment gem. Am currently trying to test my implementation by making test transactions. Here is output from my debug log: #<Payment::AuthorizeNet:0xb73a5850 @test_transaction=true, @password="secret", @state="IL", @last_name="Pine", @delim_data="TRUE", @amount=6.0, @version="3.1", @prefs="script/../config/../config/payment.yml", @city="Chicago", @first_name="Joe", @type="normal authorization", @expiration="1/2008", @required=[], @country="United States of America", @url="https://secure.authorize.net/gateway/transact.dll", @card_number="5424000000000015", @login="8888888888", @zip="43567", @address="13789 E. Elma", @relay_response="FALSE"> When I do a transaction.submit my transaction fails and when I try to do this: puts "ERROR: #{transaction.error_message}" I get ERROR: I get nothing back and my transaction fails. I am trying to understand why my test transaction is not going through and what I am doing wrong. Any ideas? -Thank you. -- Posted via http://www.ruby-forum.com/.
