I’m stuck on Stage #ri1: **List elements (negative indexes)**

When I test RPUSH locally, I seem to be getting the correct output, but for some reason when the tests are run, sometimes it says Received: “” (no content received). I’m not sure why my local environment never does this but the test does.

Hey @NIHARSIMHADRI, I noticed a couple of issues:

1. `#define MAX_TOKENS 8` may not be big enough for a long command:

1. The order here could cause problems if `curr_list` is not valid:

Thanks Andy, fixing these helped make it work.
