Identifier must be declared error

Rather that using the Microsoft ODBC error for Oracle, I tried to use the Oracle ODBC driver, in order to append data to an Oracle db.
Unfortunately, I get the error below (bottom of page)…. Does anyone know what changes that I may have to make to my Oracle stored procedure in order to make this work. I think that this may be a datatypes problem. Am I right?

{call aoppack.getloodetails(?,{resultset 9, APPROVAL_DATE, ACCEPT_DATE, PRIOR_CONDS_MET_DATE })}
OraOLEDB error '80040e14'
