I've created a quiz with a point system which return a value and then a email is sent to the initiator with the total points. I need to restrict the number of times the user can submit the anwers to 1 or 2 tries etc. How do i go about doing this?
I believe this is a SharePoint setting where you can restrict a specific field to be unique values only. So the idea would be to have that used on say a "submitter" field or people picker and it should force that it has to be unique after a submission already exist for that person.
Another option which is more of a back end thing would be to use a workflow to control this. You would have a workflow check against the list and if a matching name or title exist, just send a notification and then delete the item.
I like the first option, however how do i go about keeping that submission unique? im not too good at writing values. Maybe a pop up saying you have already submitted the request when they try the 2nd time.
