Nintex Forms 2013 - need to only allow users to submit once a day

[sburkecit]

I'm using Sharepoint 2013 and Nintex Forms/Workflows.

We have a daily COVID-19 Attestation form that users who go into an office must fill out.  But we have users submitting multiple and we are trying to stop that from happening.

We have a "My Submissions" view that already filters on the current user and sorted by most recent first.

I wanted to disable the Submit button if a submission was found with the current date in that view.  Is this possible?

Thanks in advance.

Hi,

Configure your person column on the list to show the Account of the user. Lets call this column "user" for this explanation.
Create a date column and lets call it "date".

Add a disable or Validation rule to the Submit button that looks like this:
contains(lookup("Your List","user",Current User,"date",true),Current Date)
The rule looks up the list and returns all the dates for the current user.
Then if the results contain todays date it returns true. If not it returns false.
