Hi Joe,
Thanks but it works for me:
Same in both CR Designer and my Windows Form app. And nothing unique in the parameter type.
Check your references, make sure they are all version 13.x.xxxx.xx
If you open it in CR Designer can you change the order, try setting it to be the first one, I also added an A to the name to see if it made any difference also:
Another thought, may be ODBC driver related, who's Oracle ODBC driver are you using in your DSN? CR support the Oracle client directly alsom Set Location and use the Oracle Native Driver and see it that works.
