I am stuck on trail: Add Business Logic

I am in Add Business Logic for the Build a Battle station trail...for whatever reason, when I mark my battle station project status as complete and weapons status as fully operational, it's not triggering the flow to "post to chatter" and when I verify the exercise I receive this error: In the ‘Fully Operational Battle Station’ flow, in the Start element, we can’t find a condition that checks for Weapon_Status__c equal to ‘Fully Operational’.
