This means, just as the manual says, your makefile contains a command
script (the echo) _before_ you've defined a target that the command
script should apply to.

OFFICIAL = 10 is interpreted as a make variable setting, not a command
string, in this situation so it doesn't elicit an error.

  bb> Please help.

If you still don't understand, post a small example makefile that fails
and we'll show you what's wrong with it.
