Thank you to everyone that helped. I checked everything and got it to work. 

@Mac Dude 565 I will try again. Would it be the same even if i am woring in maple 16?

@Kitonum I tried the new command but still dont get a graph for it. After I execute the command it turns blue. What do i do next, can you tell me the steps or commands i need to get the graph to show.

@Kitonum i entered the command the exact same way but the graph does not appear. am i missing something

thank you very much
