Simulation cannot run

Hello everyone! I need a little help here. I'm trying to simulate this cct using PSpice from LM338 datasheet of Texas Instrument and I'm not sure if this is the right value and graph that I should be getting? Thank you in advance for your help! cct2_run.pdf

    If you are implementing Figure 35 from the datasheet, you are missing a negative supply for the LM317 to connect to and no load to sink the current from the LM338.
