sends help

I don't know if I have hit something wrong or not. Never had this happen before. Here is my routing..... I have drums going to a buss. I have Keys going to their buss. I have guitars going to their buss. I have lead vox going to their buss. I have BG Vox going to their buss. Those busses mains are going to main out. But have a send on each of them.. as follows. Drums main out to main, then a send to a room reverb buss, that buss is going to main Keys main out to main, then a send to a different reverb buss and so forth and so forth. With this routing.. Meters jump into the red. Some parts can't hear at all, or barely. I don't know if this could be the culprit.. on the reverb plugins, I turn all wet, and turn dry all way down.. .then on the send for each track, I use the amt knob to dial in what amt I want to go there.. but I do click on level and post... Any help with this would be appreciated.. If I take out the reverb busses, everything is fine. Figured out my problem... all is good in the world
