Access a form of another nsf

I created a frameset where the frame value is a computed form name. The computed database formula of the frame points to another nsf in a subdirectory on the notes data directory. The form has an embedded view.

The above works fine on my PC but when installed on other PC, the form failed to launch and the default view of the current database is displayed instead. If I use a designer on that PC to open and save the design again, then it works properly.

The above problem does not occur when the designated nsf in the frame formula is on the notes data directory and not on a subdirectory.

Any idea how I can overcome this problem??? Thanks
