My apologies as I was just made aware that we are not receiving emails on the forum questions. I am sure that you have already done with this but for future reference, please see the response.
Did you create a multiple version form for your multiple version assignment? Is this a generic form where the students filled in their IDs. If you could send a little more detail to email@example.com with the assignment name, we would be happy to help.
Again, I apologize for not getting right back on this.
Please let me know if you have any other questions.
