Weblog Database

I'm trying to submit my 3 xml feeds to google but I don't understand the technical part of this. every time i try and submitt the feed it shows that 0 products have been uploaded. I've read for hours and tried different things but I'm at the point where I would like to see if someone can help me with this. My feeds are below and if you could take a look at them and tell me what is wrong with the feeds in lehmans terms because I only know just enough to get me by when it comes to this stuff.
