Can't get the guitar track to record but can monitor?

Hu guys, I’m new to Cubase and making the jump from garage band. I am using an iRig HD2 to record guitars but when I hit record nothing records. I’m getting a strong signal from the interface and can hear it but once I hit record nothing happens. I’m sure it’s something I have overlooked but I cant figure it out. Any help out would be great

Hi and welcome,

do you have an Audio track ready? Is the Record Enable switched On on the Audio track? Can you see the cursor is moving, while recording?
