Open file on desktop through GO

Hi all,

I'm trying to do following:

1) FM Go performs a script on an open, "master" database (hosted on a Desktot computer with Mac OS X and Fm Pro 14 Adv) -> OK

2)  the "master" database (always open and reachable) should open a second ".fmp12" file ("slave") which is in the same folder as the "master" file on the desktop computer -> NO

Apparently the "Open File" script step when run by the "master" database but called from FM GO doesn't work (can't open the "slave" file).

Open URL script step run from the master file doesn't work too, as it expects the "slave" file to be already open.

Is what I'm trying to achieve possible ? How  ?

Thank you in advance !
