You're on the right track, and the code looks good. 
Bummer.
The challenge just wants you to use a for loop to log the numbers to the console. So, first, you need to delete the variable you created that was not asked for.
Next, you should be using console.log() in the loop, not a variable.
With that in mind, the code should be "logging" out each number separately, not adding them together (again, something the challenge did not ask you to do.)
So, you do have all the correct code, you just have some that isn't asked for and one line in the wrong place. Below is the corrected code for you to compare to the notes I provided above. I hope it helps.
for(var j = 4; j <= 156; j += 1) {
console.log(j);
}
Remember, Challenges are very specific and the instructions need to followed exactly or the Bummer will appear. Other than that... good job!
Keep Coding! :)

I think the problem is because the value of write has not been initialised. When I tried your code I was getting NaN printed to the console. Because write has no initial value, it doesn't know what to add on to j as it goes through the loop. Simply changing the first line to:
var write = 0;
meant that 12240 was printed to the console.
