Why won't my document validate???

There isn't much to say about today's class. At the beginning of teh class, when Mr. Arkin taught us the keyboard keys that could make our jobs easier and faster when working on the computer, it did help. I beleive that Iwill be able to use these techniques. This period Iworked on fixing the errors on my page and then trying to validate my index.html. But. when I tried it still told me that I had 16 errors even though I had made corrections and followed the html template. I am hoping that Mr. Arkin can take a look at tomorrow and that way I can get it validated and on the web. I looked to see if i missed anything using the index.html of other students who did get their index.html's validated, but it was the exact same. When I tried again after. It said that it couldn't verify the document. It is really confusing right now. I just need to take care of this problem and it would be like the world made sense again and I could carry on with the rest of my work. I hope I get this solved so that I can get on with the rest of the website over the weekend and possibly finish my whole site. I am a very hopeful person!
