It is possible that the problem lies with how this field was defined within NFS Designer.
Contact your naturalForms Administrator.
Administrators, please check the the field in NFS Designer to ensure that at least one option is selected from the following for a Text Field:
- Allow Alpha
- Allow Numbers
- Allow Date
- Allow Time
- Enable Handwriting
If none of these are selected, the naturalForms app will close down every time a user selects this field on a document.
