Actually the closing bracket is on line 6.

I am not sure I understand, the Hours are in the SC-Details table but not the hourly rate it is the amount of hours worked. Here is a description of the tables:

SC_details

Sc_number   NOT NULL          Number(6)
Line_ID     NOT NULL          Number(6)
Part_ID                       Number(6)
Service                       Varchar2(255)
Technician                    Varchar2(30)
Hours                         Number(6)

For those of you who caught my '-' mistake, it was corrected with '='. Thank you. But it still did not solve the problem. Am I missing an easier way of doing this?
