Thank you!!! You fixed it
I was having trouble figuring out the syntax for a single choice submission field. (1,text, 2,text) and was editing/saving the submission quite frequently. Maybe 6 times over two minutes. I don't remember exactly what I was changing, but I am not familiar with the unlock_fields parameter.
I do believe you're correct because I did notice a submission while I was editing the form.
Thanks again!
