I have a Nintex form in SP 2016. There is a list lookup field that allows user to select multiple check boxes. However, I only want the user to check only one checkbox. How do I validate that?
I want to do the validation within the Nintex form - not using a workflow.
Thanks in advance.

Why not just change the Control from a Drop Down to Option Buttons?
That way, only ONE can be selected
Thanks, but I need to make it multiple check box. I found the solution.
Add a Validation Rule:
length(SystemName) > 1
This rule shall fire if the user selects more than 1 item.
I found the solution from the following blog,
