Thanks larkost. Obviously I got both of them working on the same file just placing it on one computer Public folder, which works albeit sounds like a cheap trick… I saw the Open Remote menu item on Filemaker but while I can find the other Mac on the LAN I can't see the .fp database file no matter where I place it, that's weird, huh?
Thanks also about the Access warning flag… Needless to say Access is out of the equation, while the Macs are intel Macs there is no plan to run Windows on them.
