Forms - Getting sum of values in the lines field

Question

Hi
I have a form which is not based on any table/view
The user has some line level details and some header level details. on save/submit button it should be saved in different tables/columns
Line level details:
It has say two fields. Item and item count.
There can me multiple lines so each new item is entered in a different line and corresponding item count in the respective field.
Header level
We have a Total item count field which has to count the total of all the line item count.
How can this be handled as this is not based on table and this value has to change each time the user enters new line.
I have made a global variable( as the total count) and on when validate trigger of the line level item count, I add that value to the global variable.
But there are some issues like if the user goes back and decreases or increases the value. then i have to put some further logic so that it does not give issues.
Any other way to achieve this?

Answer 1

simply put the summary column in Detail block which totals ur Items in detail Oracle will handle automatically
Use the same field to transfer to Another table
