Tell us what’s happening:
Hello,
I have a problem with the Metric-Imperial Converter project on repl.it and when I try to send my solution, freeCodeCamp says that the tests are not complete and passing. But I have absolutely no idea why. I have made those tests likewise other people (youtube and so on). But it still doesnt work and its so frustrating. Below you can see my tests. Please give me some advice. Thanks!!!
