Su Doku: Can you solve this puzzle?

I'll have the answers on the audio portion.

What has to happen is that in every row and column each number 1 thru 9 must appear, but only once. Also, in each region, a region is a square three cells tall and three cells wide, each number can appear only once. The big square is nine cells wide and nine cells tall. There are three groups of three regions as well.

Have fun.
