[JMWE] adds a value to a field, from the subtask field to the parent field

[RIZKY JTUASIKAL]

I have 1 Parent and 1 Subtask, here are the details:

Parent (Project):
Project has a field, named TOTAL BUDGET.

Subtask (PCRF) :
PCRF can be created repeatedly if there are changes from the budget side.

For example: PCRF 1, PCRF 2, PCRF 3 and so on.

**As long as the Parent status is not Completed.

And last, this subtask has a field, named APPROVED BUDGET.

I have the following example cases:

1. The user create the first PCRF subtask, with the value of the Approved Budget field is 100.

PCRF 1.

Approved Budget = 100

Then, after the PCRF status has been Completed, the value of 100 will be stored in the Parent task.
It will be stored in the Total Budget field.

Parent
Total Budget = 100

2. The user create a second PCRF subtask, with the value of the Approved Budget field is 50. 

PCRF 2.
Approved Budget = 50

Then, after the 2nd PCRF status becomes Completed, the value of 50 will be summed up with the value in the previous Total Budget field.
(50 +100)

So, the Total Budget field value will automatically become 150.

Parent
Total Budget = 150

The question is, how do we make processes 1 and 2 above run?

What post function do I need?

please help,
Thank you in advance.
