I'm pretty sure jack is french, but i keep getting an anomaly every time. ANY IDEAS? Thanks. I need to find out the first names, last names, doctor they saw, and the doctor's profession. All the information is given, you can get a single answer with it. It might be helpful to draw a grid, with 6 grids for all the combinations of categories. (any help will be greatly appreciated, however if you answer with something like "asdf" just for the 2 pts. you're breaking yahoo's terms and i will report you).
