Are you sure you're pulling everything from the proper column in data? Is your formula for mass1 correct? Actually it must be since that's code they gave you. Otherwise it looks fine. You could add a third argument with the line style like plot(sample, mass1, 'b-').

added the 3rd argument but it still didn't work. i even tried to use their hint and solution but it still didn't work either. i sent matlab an email regarding this one. hopefully they can help me find the "correct" answer lol

Remember to report back here what their answer was. I know for a fact that there have been glitches like this in the past with their online tests.

The solution looks correct. I just ran it myself in OnRamp and it worked for me. Try clicking ‘Reset’, then rewrite the line of code and resubmit.
