>>The result I am getting is 6 for the person.lname count and 18 for the sum of workhour. It seems like my person.lname count is count the number of records in Pinfo table. What I really need is a count of 2 for number of person records found and a sum of 18 for the workhours found. Can someone help me figure out why my count for person.lname is wrong and how I should formulate this query.

Hi Peter,
I tried that and it gave me
Cnt_lname Sum_workhour
3 8
3 10
The results I'm hoping for is
Cnt_lname Sum_workhour
2 18
