Error 3 - Command is unavailable (for example, wrong operating system, wrong mode, etc.)

[Don Sloane]

I’m working on a Mac OS X 10.9.3 and have a FileMaker 13 Pro developed app that I’m trying to implement a SMS solution in. I’m getting an Error 3 message – Command is unavailable (for example, wrong operating system, wrong mode, etc.). and will be implementing on iPad as well.

 

Can you give me a hand on what I need to do to get this to work?

In what context? Is this in a script or a manually entered command?
