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.
You are not able to use multiple version forms for a test that is not a multiple version assignment. I would have to see the forms, but if your forms have version bubbles on the form, you could try to bubble in Ver 1 and then scan for the district assignment - IF the form is a generic form. if you have the assignment name on the form you created, then that form will not work for the district assignment as GradeCam is looking for the assignment you created.
Again, I apologize for not getting right back on this.
Please let me know if you have any other questions.
