Wants to add a channel to an existing panel screen on AddObserver Builder.

Q:
I'm trying to add a channel to an existing panel screen on AddObserver Builder.
I select the CHANNEL tab in the configuration dialog box, insert a row, and then I want to select the channel to add in that row, but the channel I want to add doesn't appear in the dialog box.

A:
In the configuration dialog box, first select the HOST tab, and then press the Get info button. Then, select the CHANNEL tab, and add the channel.
