Trying to use 3 input parameters and getting errors

Question

The code I am using was modified from code that worked using one parameter. Below is the code. I don't have a problem until I go to add values to the collection object. Then those 3 lines error, which I think also causes the next 3 lines to error.
Does anybody know how to fix this?

First-
This program opens and reads the file CReg.txt, which contains;
*     1. Cash code
*     2. Bank code
*     3. Trans Ident number
4. Vendor number
5. Check Number
Second -
  Open CeckRegister.rpt using 3 parameters Cahs_code, Bank_code, and
Trans_Ident, then export as (filename).pdf. Where (filename) is
Vendor_number plus today's date plus the check number. These 3 fields
are separated by '_' to make the name readable.
Loop until CReg.txt is empty
Lawson tables read by Crystal Report:
     1. CBCHECK

     3. APINVOICE
     4. APVENMAST
     5. APVENADDR

Answer 1

That did not get any errors, but it did not return any data in the report.
I think that this is loading one value on top of another, so at the end only the last parameter is loaded.
This is what I have now for code.
//Open report.
     ReportClientDocument reportClientDoc = new ReportClientDocument();
     reportClientDoc.open(REPORT_NAME, 0);
//We will be using the ParameterFieldController quite a bit through-out the rest of this function.
     reportClientDoc.getDatabaseController().logon("procure","procure90");
     com.crystaldecisions.sdk.occa.report.application.ParameterFieldController paramFieldController =            reportClientDoc.getDataDefController().getParameterFieldController();
     paramFieldController.setCurrentValue("", "cash_code", new String(args[0]));
     paramFieldController.setCurrentValue("", "bank_code", new String(args[1]));
     paramFieldController.setCurrentValue("", "tran_code", new String(args[2]));
     ByteArrayInputStream byteArrayInputStream = (ByteArrayInputStream)reportClientDoc.getPrintOutputController().export(ReportExportFormat.PDF);
//Release report.
     reportClientDoc.close();
Does anybody have any ideas on how to load 3 parameters?
