A Variable Set contains all your Smart Preflight variables that can be used within your
Preflight Profiles. You can create more than one Variable Set and each set can have multiple
variables defined. However, you can only run one "active" Variable Set at a time within
PitStop Pro. It is recommended that you keep all your variables within one Variable Set unless
you are also working with PitStop Server.
Note: If you use variables that are contained in
different Variable Sets within a single Preflight Profile, only the "active" Variable Set
variables will contain their default values. Variables used from inactive Variable Sets will
be blank.
