I am trying to setup custom validation on attachment control in Nintex Office 365 forms.
Here are my rules:
1. I have a panel that will be displayed or hidden based on the value choice type control value.
2. If choice = yes, I display panel.
3. The panel has attachments control.
4. I need to validate that the attachment control has 2 attachments only when choice type dropdown's value = Yes
I saw some JS functions on how to count attachments. But I don’t think we can run custom js functions on attachment control in Office 365 forms. Is it possible to setup this validation in form submit?
