Form is allowing submission with required fields blank

[ab50439]

I have a submission form with two tabs.  Unconnected Choice Buttons control whether one panel is displayed or the other.  The SharePoint list has a few required fields which should never be blank.  On the form, these are all on the first tab.  I'm finding that the form is allowed to be submitted with the required fields blank as long as the second tab is selected when it's submitted.

How do I make the required fields required even when hidden? 

(All the previous similar topics seem to be for the opposite problem.)

Hi,

What you are seeing is expected behavior.
If an unconnected required field is hidden is makes it not required.
The only way to achieve this solution is to connect the hidden controls to required columns.

The required fields are connected but may be hidden.  When I referred to an unconnected field, that's just the buttons that act as the tabs, not an actual field.

Maybe I need to explain this more carefully?

My SharePoint list has several mandatory fields.  These are set as required in the SharePoint list settings.

I have a Nintex form for this SharePoint list.  It includes these mandatory fields (and other optional fields), and they are connected to the SharePoint list fields.

Some of the mandatory fields are within a Panel (the Nintex Form Control).  Based on a Rule, sometimes the Panel is set to Hide. 

The problem I'm having is that when the Panel containing the mandatory fields is Hidden, users can successfully submit the form with the mandatory fields blank.  This is breaking my team's processes and causing delays.

I need a way for the required fields to be enforced, even if the Panel they're within is set to Hide.
