Sum Measure from a aggregated summarize column

Hi , My appologise, 

My base data is for one use case jobid  95676

JobId  | Potentialhours | Session_StartDate | WeekEndingDateFriday
95976 | 10.000000        | 2024-09-16           | 2024-09-20
95976 | 10.000000        | 2024-09-13           | 2024-09-13
95976 | 10.000000        | 2024-09-17           | 2024-09-20
95976 | 10.000000        | 2024-09-09           | 2024-09-13
95976 | 10.000000        | 2024-09-18           | 2024-09-20
95976 | 10.000000        | 2024-09-04           | 2024-09-06
95976 | 10.000000        | 2024-09-12           | 2024-09-13
95976 | 10.000000        | 2024-09-26           | 2024-09-27

Then I need to Gregate this data per week

JobId  | Potentialhours | WeekEndingDateFriday

95976 | 10.000000        | 2024-09-20

95976 | 10.000000        | 2024-09-13

95976 | 10.000000        | 2024-09-06

95976 | 10.000000        | 2024-09-27

At the End I would like to get a card with a measure that gives me 40 as total or a total of all jobs ID
