Hi Sky, Thanks for the helpful advice.
Even with your syntax, I am still getting an error, albeit a bit different. The error now says simply:
"The file MyFMPDB could not be opened.
Either the host is not available, or the file is not available
on that host."
Also, this example from the link you sent should work, but it isn't.
Run the script ListClients from an open file named Clients.fmp12:
fmp://$/Clients.fmp12?script=ListClients
