3dr drone video

Hello everyone, please bare with me, I am BRAND NEW to flying drones, and the 3DR Solo is my first drone. I love how easy it's been learning how to fly it, and how nicely it responds to commands. My question is about video capture? Maybe I'm just not looking in the right place for this...

I have everything connected to a 3DR Solo with gimbal but cannot get the GoPro Hero4 Black to record. I can see what it is looking at, the gimbal is tilting with the controller, the drone is flying, but the message on the controller is "Recording Inactive?" What am I doing wrong?
