Need Help setting Rule for field to require Attachment before allowing a selection from a drop down,

Question

I have a form field which has 3 different selections in the drop down, In Progress.. On Hold.. and Completed.

Since the form is opened many times before marked complete, I do not need a code that requires an attachment before submitting. I need a rule which would make having the attachment which we want to require attached before the "Completed" status would be selectable from the drop down and the form submitted.

Answer 1

I was able to do this with a very small workflow that runs when an item is created, and when it is changed:

In the workflow itself, I checked the conditions you specified. If those conditions are not met, the workflow will adjust the status (I called the column "Choice") to a different status (I chose "On Hold"), and email the modifying user that their status was automatically changed due to not having an attachment:

Please let me know if this helps you!
