When i look in the debugger in IE I see the code file is not being referenced in [screenshot 2].
I am using Nintex Forms 184.108.40.206, SharePoint 2013 on prem.
Solved! Go to Solution.
I could be that the file isn't referenced. In your includes the path could be referenced wrong and not pull up that file that has that function. Could you show some screen shots referencing the configuration?
Also, what extra validations do you need to do? That blog is out of date and you can apply a rule to multiple controls.
