Help with Metric Imperial Converter

Tell us what’s happening:
I am working on the Metric Imperial Converter challenge, I haven’t completed the tests yet. I was trying to use the live app but it doesn’t seem to send any input back to the server.

Also, how do I run unit/functional tests on glitch? I added NODE_ENV=test in .env file.
