I have a PDF form and it has a Due Date field which people seem to keep forgetting to fill in.
I know you can make a field "mandatory" and it turns it red(ish), but I fear that won't be enough to have people fill it in. Is there away to prevent the form from being saved unless that's filled in? Maybe even have a message pop up that says "Please fill in Due Date prior to saving" or something? Or any other way to 100% ensure the due date is filled in prior to them submitting to me through Outlook email?
