Here's a setup for Powerball using just a few data sets to determine some positions.
The data set has to lag the current draw in history by one drawing so you can see what position it was in just prior to the drawing. You will pick ball numbers based on the previous draw's positions.
Next drawing is based on 06/21/08 - 01/02/08 data set and those positions were based on the previous draw's data set, ect, ect...
