Use the following Java code to check the value of the SALARY input column before adding it to the output field TOTAL_SALARIES:
// If value of SALARY is not null if (!isNull("SALARY")) {      // Add to TOTAL_SALARIES.      TOTAL_SALARIES += SALARY; }
or
// If value of SALARY is not null String strColName = "SALARY"; if (!isNull(strColName)) {      // Add to TOTAL_SALARIES.      TOTAL_SALARIES += SALARY; }
