problems with recording

I feel like a noob. I can't figure out how to record on Reaper now. I've recorded some guitar and vocals, but now I can't get EZ drummer to record at all. I armed record. I turned on the monitoring. I can hear the drum. However, when the bar goes across the timeline, there are no valleys or peaks or anything of that sort. When I replay, there is no drum sounds. I'm almost positive it's something childishly simple. Any ideas?

As you said "valleys or peaks" I see that you want to record the EZDrummer audio. That's the Output from the track. So right-click the RecArm button on the EZDrummer track and select "Record output" then a sub-option.

bugger - you're on fire today, dark!
