Display total detail in Master

[AAA]

Hi, current i can't display value of total detail Databand in Master Databand
I want to show as follows
Example:
First record:
(Master)
TextFiled = 8 <---- This is total Quantity of Child
(Child)
record1: Quantity = 3
record2: Quantity = 5

Second record:
(Master)
TextFiled = 10 <---- This is total Quantity of Child
(Child)
record1: Quantity = 4
record2: Quantity = 6

Third record:
(Master)
TextFiled = 6 <---- This is total Quantity of Child
(Child)
record1: Quantity = 2
record2: Quantity = 4

Thanks
