Can't get Rising Inputs to work

![alt text][1] [1]: /storage/temp/171171-splunkerror.jpg Can anyone help please? I can't get a rising input query to work at all. Batch Inputs work fine. Rising Inputs always gives me this error: External search command 'dbxquery' returned error code 1. Script output = "RuntimeError: Failed to run query: "SELECT * FROM (select * from (SELECT BWTXNID,CURRENCY FROM ALANK_HOSTTXNREQUEST order by bwtxnid) {{WHERE $rising_column$ > ?}}) t", params: "None", caused by: Exception(' java.sql.SQLException: Missing IN or OUT parameter at index:: 1.',).
