+3Hello -
I used SP 2016 On-Premises, I would like to validate the attachments field if empty on the submit form. I used a validation rule below, but none of them are working. How can I validate if attachments empty on the submit form in Nintex New form? I’m appreciated for your help.
not(Attachments)
not({Self})
Attachments < 1
isNullOrEmpty(Attachments)

+7For SP/Nintex 2016 on prem, in a form, what is the rule formula to ensure attachments are added IF a certain field (which is named and inside a panel) is not null. In other words, If the user enters data into a field (single line of text), Attachments are required. Otherwise Attachments are not required.
I created a rule on the SUBMIT button to Invalidate with the following formula but it’s not working as desired.
and(not(isNullOrEmpty({namedControl})), isNullOrEmpty({ItemProperty:Attachments})
+22Hi
{ItemProperty:Attachments} looks at the SharePoint list attachment column and not the attachment control.
