I keep getting Bummer when the code is correct. I ran it in the Workspace and it worked perfectly.

On the For Loop exercise to console.log 4-156 my code is correct but it keeps saying I'm wrong. I ran it in the Workspace from the previous video and it worked perfectly. It wrote the numbers 4-156 to the console. for ( i = 4; i <= 156; i += 1 ) { console.log( i + ' '); }

script.js 
for ( i = 4; i <= 156; i += 1) {
  console.log(i + ' ');
}

Hi John, it's just the space you are adding to each number, I'm not sure how the engine tests the output, but the solution is just to remove it. Also, make sure to include the var (or let/const) keyword when making variables, while it won't hurt here without it, in the future it may create issues :)

for (var i = 4; i <= 156; i += 1) {
  console.log(i);
}

Thanks Umesh. I found that out also. Good comment on declaring the var in the For condition but the videos don't do that. Thanks for the insight!
