Once again, in order to use our newly created Flow Definition, we must move it to an Active state.
Step 1 (Move Status Button): Press the Move Status Button to move Flow Definition from Pending state, to Active state.
After you move the Flow Definition to Active state, your screen should look like the one below.
You will also notice the extra icons available to toggle the Flow Definition state. The Flow Definition state can be toggled in the following order:
Pending 
Active 
Archived
Archived 
Active 
Pending
Archived State - This state is used to make a Flow Definition inactive within the system.
