I'm sorry, but I have no idea WTF I'm looking at here. Did something get corrupted or is this actually what you're working on? (Sorry about the small size - my laptop screen is quite small, so any bigger than that and I can't see everything.)
1. Why are you trying to use sheet metal here?
2. Your sketches are remarkably unconstrained here. Sketch 1, for instance, is missing 49 dimensions / constraints. This is not a good way to start off a model. (Gawd, I can't believe I'm actually saying that ... I sound like JD now!)
3. Pretend the "Move Face" tool doesn't exist. No, really - I mean it. If you need to use that tool, then you didn't plan ahead well enough and you should probably start over and chalk the wasted time up to a learning experience. I'm not being sarcastic at all.
4. What are sketches 3, 8, 9, 10, & 12 doing? They're just random points in space?
Those are just the questions I can come up with right now. At this point I'm pretty confused about what it is exactly you're trying to make. Can you clarify a little? I'm not trying to be a jerk here, I really don't know what's going on in this part and need some more info.
In the meantime, check out some of JD Mather's tutorials, and work through the tutorials that ship with Inventor.
