Hi everybody. I’ll try to explain correctly what’s my problem…
Even at the first step i can’t run the code. I don’t know why.
I have simply to change the word “Hello” with “Hello World”, but when i put on run the tests… Maybe i’m doing somthing wrong, or there is some setting that i have to change…
I’ll appreciate every help!

Is the browser Edge? For some reason Edge seems to be bugged, and for some reason the run tests button doesn’t seem to work in certain browsers. If that’s the case it possible to try in Chrome?
