Can't send a group track audio to an audio track

I want to send a group track audio to an audio track but the group channel doesn’t appear in the available inputs of the audio track. Any help?
PS: My proccess is on this video from 1:51 to 3:15

My DAW is Cubase 7 AI, in case there might be a restriction…

Hi and welcome,

Any output channels don’t appear as the Input channel, if there would be a feedback. Make sure, you are not using the same Channel as an Output, of the track, where you want to use it as an Input.
