Hello. I just stared with APEX.
I have a form where a user can choose 1 value from a Popup LOV. Next to it is a number field where the user writes the quantity he wants to get from said item (max value is 5 in the number field. I have that type of form 5 times in the same page.
My request is to create a validation that makes sure that the total quantity of all items is less than 3
Thanks in advance
