ahhh.. the good old password issue.. I ran into the same thing a while back.. Here is how users and passwords work in FM..
It passes the user and password that you are logged into the database as. So you need to have the same user and passwords in all databases or use a script to switch users before opening... and then when they go back to the original database switch back..
awesome, thanks. That did it, I added the same user and pass to both DBs.
