just got it to work. There was a mistype in my jquery references.
are there any issues with this being added to nintex forms 2016 on SP 2016 on prem? I have had no luck so far.
We did find that we can increase the session timeout for the web page security validation in central management. Doing this has stopped the form...
This is all I see when I am in the text field settings.
Thank you for this solution. Works great!!
