Why does the word “MISSING” show up in filenames and index fields when the field is blank?

You can change this to whatever you want it to say when a field value is left blank. To do this go to “Job Options” then to the “Index” Tab now click “Advanced Options”. In the middle of the window you will see a box labeled “Use this value whe a field is empty” just change “DEFAULT” to whatever you want (including leaving it blank) and click OK. Now the next time you have a blank field value for a filename or folder name it will have your new message.
