# Cannot use a target to enable a flag that is disabled in Harness

## What's going on

In Harness Feature Flags, you can add a target rule to disable an enabled flag, but not to enable a disabled flag: target variations are only evaluated when the flag is ON. It looks like a bug but it is how the evaluator works.

## The verified fix

Flip the flag ON and make the default rule serve False, then add target rules that serve True for the users you want. That gives you off-for-everyone except specific targets, which is the intended way to do it.
