Hi all,
I hope you all are doing well. One of the forms we are using is throwing the error below:
This form is a daily form that doesn't do calculations or has a hidden required field like this post suggested could be a cause. We're currently on Forms 11 version 11.0.2307.40547.
It doesn't seem to happen often but every other day.
Staff state that they get this error on tablets, but have no issue on a computer. They do input a value into the required field before submitting despite the error in the screenshot.
I've looked at the logs and it's only happening with this specific form. I filtered the event viewer to event ID 9320.
The logs constantly show Position: 4, 29 and 30. What does position indicate?
Any insight would be appreciated.
