Unable to record electric guitar


I have recently purchased Cubase Elements 8 and a Steinberg UR 12 and am rather frustrated and have wasted hours trying to work through the numerous videos and manual. :frowning:

All I want to do is plug in my electric guitar and record it. I was expecting the product to be a simple plug in and record. Unfortunately, the product is not that simple, after watching numerous you tube videos I still can not find how to record my guitar.

I can hear it through the headphones but it does not record when I select what appears to be the record button.

Can anyone point me in the right direction
