If you want to include the commands from other profiles into your current profile, click on the '...' and select the profile(s) that you want include.
There is also the global profile setting available from the Options screen as described earlier - you don't need to include those with your profiles, they're automatically included.
If you search VoiceAttack's help document (press F1 while VoiceAttack has focus), search for the option names ('Include commands from other profiles' and 'Global Profiles') for more information on what these features are for and how to use them.
