Hi,
I have a need to add an automatically increasing number to a document each time it is opened. The document (a coating inspections record) is accessible by 5 to 6 people from different computers and each person wont know what number the record should be up too.

It is a requirement of this project that i cant individually assign a numbering system to each person, i have to follow a sequence... 1000, 1001, 1002 etc etc.


I've never had restrictions like this placed on me before and frankly have no idea how to make it work.
Any help would be greatly appreciated.
Thank you.
