Hi compactmad,
I can post some code to update an Access table from Word if you like but if that's all you're using Word for, it's way too much complication; it might reduce multi-user problems, but it certainly won't avoid them and you'll still have to code to deal with them (probably more complex code but I'm not well up on multi-user Access systems).
I'd go for the Access Form, and if you have multi-user (or any other) problems post again in one of the Access fora (Forms, perhaps) where I'm sure you'll find some answers.
Enjoy,
Tony
