It doesn't seem like it is a valid Sudoku. There is more than one solution.

You need to fill out all the possible values that can occur in each cell. Some programs do this automatically. I am very fond of Hodoku for this:

When you put in all the possible values you will see a number of Naked Singles which are circled.

I did a bunch of tutorials that may help you learn about puzzle solving techniques like Naked Single:

Just cut-n-paste the URL into your browser to see the list. I hope they help you!
