Only allow users one choice per user per day

[tonysommer]

I have a calendar gallery and a form that has 4 choices. I only want those 4 choices to be selected one time each day. How can I restrict users from being able to make more choices than the four presented?

For instance User A can choose 1-4, and if User A selects choice 1, then User B cannot select choice 1 for a full day. Is that possible or do you have any insight on how to restrict users in that way?

My thought is to disable the submit form button unless a user selects a choice that has not been selected for that day.

Added screen shot to help with troubleshoot.

Hi @tonysommer ,

Do a CountRows on a filtered list based on your data with the date in it. So using YourList and YourDate

If(
   CountRows(
      Filter(
         YourList,
         DateDiff(
            YourDate,
            Today(),
            Days
         )=0
      )>0
   ),
   Notify("You cannot select another one",NotificationType.Error),
   Whatever you do now
)
    

 - please watch commas/brackets as I free-typed it.

I'm not exactly sure I understand completely. Does this allow the notification to happen if somebody chooses a license that has already been chosen? Any way you can elaborate on what this would do?

Hi @tonysommer ,

Updated a bit below - I was showing you the syntax for testing that something in your list had not been done today

If(
   CountRows(
      Filter(
         YourList,
         YourActivityName = "The one tested" &&
         DateDiff(
            YourDate,
            Today(),
            Days
         )=0
      )>0
   ),
   Notify("You cannot select another one",NotificationType.Error),
   Whatever you do now
)

You would have to test the four.

Sorry yes, this has helped steer me in the right direction. Work has been crazy and haven't been able to get to it until today.
