Update file name if upload file present
I have an update page with two fields that can be updated. One is a file field that I have an Upload sb attached to and the other is a description field. I want to set it up so that the user can change one or both fields - and, if they don't change the file field, the current file value remains.
So far what's happening is that if I don't select a new file for upload, the current file field value is removed and an empty string is stored in the field. I have a hidden form field that holds the current value. How do I make sure that value is used if there is no filename in the upload field?
Thanks - Joe
