I created a column validation by opening the Nintex form in the form designer.
Clicking the control settings of the "singletextbox" I added this condition in the "custom validation" field like shown below,
When I input a values less than 6 it never shows me a custom error message "6 digit".
1.Is anything that I am missing to fill/configure.
2.I tried using a column validation in the sharepoint list settings --> column --> column validation but it also never report error.
But if I dont open the form using the Nintex form I could see error message i.e through Sharepoint form.
Whatever condition I check it all works in the Sharepoint form.
