Hi I got the error when calling out the below, and i found out there were 2 employees with the same first and last name, in such cases, how do we call out both of them? SET @v_emp_no = 0; CALL employees.emp_info("georgi","facello", @v_emp_no); SELECT @v_emp_no; Error Code: 1172. Result consisted of more than one row 10001 1953-09-02 Georgi Facello M 1986-06-26 55649 1956-01-23 Georgi Facello M 1988-05-04

the function results in zero output please specify why

Hi Jaycus, thanks for reaching out! Could you please provide a link to the lecture your question is referring to? This is the data visualization course and the building a dashboard in excel section, which features a data set from an FMCG data base - which doesn't include the rows you've provided as a screenshot. Also if you did post your original question in another course (possibly SQL), please let us know, so that we can address the issue. Best, 365 Eli

You need a space after "Sum of ". That should solve that error. **You also need to lock the 'Volumen' cell $B$33 (lioke that) so you can drag to the remaining cells and not get 0.**
