Hi, Is it possible to stop user to create more than one item using Nintex forms(Responsive) in Office 365 (Sharepoint Online)?
I tried to get values for the Created By equal to Current user but the List Lookup always gives "Please select a value as default and my name" if there is an item present. I wasn't able to created a rule to check if the List Lookup has value or not.
I have tried lenth() but it shows 0 for the default value
Can you please let me know how to acheive this functionality?
Create a new column ex unique_user and type Person or Group type
Under additional column setting Enforce unique values set to YES
Store the user name value into person or group field .
