Could you please advise how I can perform this validation.
I have a sub-list that has a column called receipt attached. As each line is added, the user can check this box or leave it unchecked. If they leave it unchecked, I would like to do either of the following:
1 As they add the sub-list line, require that they include an attachment against the sub-list if the receipt attachment is unchecked OR
2 Display a message that advises an attachment is required if not all of the sub-lists have the receipt attached checkbox checked.
