Once the Data Source window opens up you will see several parameters created by the Query Builder in the Where section. The two parameters there indicate that the Grid should be filtered by two keywords: s_emp_name and s_department_name. Both of those keywords come from the Search form and will be matched against the emp_name and department_name fields from the database respectively. However, we would also like to search by employees' titles, and since the department_name was changed to a ListBox it will need adjustment as well.
Click on the title parameter and move it upwards (^)
Your final Where/Search parameters screen should look like the one shown here.
