Is there a better slope field program for the TI 83 calculator?

[GreenPrint]

Hi I was searching for a slope field program for my calculator and found this one

http://www.math.lsa.umich.edu/courses/116/Calculator/TI83/TI83-SF.html

for some reason I can't get it to work. When I run it I only get one line row of lines at the bottom of my window when it graphs it. I don't get the whole slope field just one row. Thanks for any help. Not really sure were to put this so i just put it here.
