PB 12.5 Soap Execution Error

Question

Does anyone know why I am getting the error is bold below?  Actual error message could not be attached.
I am getting the following error when I run a Soap Proxy Client from a PB 12.5 application :
The essential part of the error is:
Error Number  0
Error Text = Unknown error, problem with Soap Client
Listed below is the script from the event that fails:
//Declare Soap objects
soapconnection l_conn
proxy_basichttpbinding_icardloadingservice      proxy_obj
__authorization                                              ltns_authorization
__transaction                                                ltns_transaction
__transactionresponse                                    ltns_transactionresponse
LONG ll_log, ll_return
STRING ls_endpoint
l_conn = create soapconnection
ll_log = l_conn.SetSoapLogFile ("C:\mySoapLog.log")
ll_return = l_conn.CreateInstance( proxy_obj, "proxy_basichttpbinding_icardloadingservice" )
ltns_authorization.idbranch = "A00070"
ltns_authorization.iduser = 3159
ltns_authorization.password = "#######"
ltns_transaction.accountnumber = "A1111"
ltns_transaction.amount = 100.
ltns_transaction.branchid = "A00070"
ltns_transaction.clavereceiver = "1234567"
ltns_transaction.senderid = 1
ltns_transactionresponse.accountnumber = ""
ltns_transactionresponse.code = ""
ltns_transactionresponse.idbranch = ""
ltns_transactionresponse.idsender = ""
ltns_transactionresponse.ws_message = ""
ltns_transactionresponse.passwordreceiver = ""
IF IsValid(proxy_obj) THEN
ltns_transactionresponse = proxy_obj.createtransaction(  ltns_authorization, ltns_transaction )  <===ERROR happens here!
ELSE
  MessageBox("Error","Proxy object is NULL")
END IF

Hi Bob,
Thanks for the suggestion.  I downloaded SoapUI as you suggested and ran the method that I was testing and the response structure was correctly populated.
The problem remains that from a PB application, I get the same error as I posted above...Error Number = 0, Error Text = Unknown error, problem with SoapClient
Any ideas?
