Why won't this parse? The code appears right?

Really don't understand what's going wrong here. shouldn't this write to the console without any trouble as a basic command?

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

Your error is in the second part of the loop -- omit the 'var'

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

I must have been staring at this for 30 minutes without working it out. Amazing what fresh eyes can see! Thanks!
