I need help on this.
I want to validate an attachment in repeating section. User can click the add item if they want to add extra attachments.
Let say:-
1) if backdate = yes, show AttachmentSection. (previous i hide this section)
2) How to validate user has attached either 1 attachment or 2 attachment after section appear in screen? Because repeating section will set the * (Cannot Be Blank) in every attachment even the attachment box is empty.
3) how to skip the validation if backdate = No and this section has hide.
Thank you. I am poor on this logic.
