Using Office 2003;

I'm sure this issue has been posted before; I tried
searching for it but I'm still looking for the "ideal"
solution. Here's the business case:

-Forms are used by a wide variety of users over a
network at multiple locations;
-Form numbers must be six digits in sequential order
and unique;
-Due to auditors, need to capture who uses each form;
-Forms are built in MS-Excel per boss requirement;

Right now, when the forms are opened a query to
Ms-Access returns a form number and records the
user login ID at the same time in Access. The number
is then written into the MS-Excel form.

This works well 99% of the time. Every once in a while,
just enough to make you crazy, a form is generated
without a number, even though my code does an edit
check specifically for this. This issue is sporadic and not
limited to any particular user, time of day, day of week,
etc. My program locks users out if macros are not
enabled by displaying a splash screen on open/exit so
user cannot do anything if macros are disabled.

Does anyone have any suggestions on how to make this
more full proof? Ideas for improved numbering systems?
I've seen something out there about a Numbering Add-In?

Due to budgeting constraints I need to build a solution
using MS Office products we alreay have (XL, Access, Word).

Any help appreciated, regards,

East-coast hopeless.
