This is correct in my browser but not on here? Please help.

var numbers = '';

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

script.js 
var numbers = '';

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

You're already incrementing i in the condition in your for loop, so you can just use i to print to the console inside the for loop. Right now, while you're still technically getting the numbers, you're combining them all into a single string before printing them, like this:

// output:
456789101112131415161718192021222324252627282930313233343536373839404142434445464748495051525354555657585960616263646566676869707172737475767778798081828384858687888990919293949596979899100101102103104105106107108109110111112113114115116117118119120121122123124125126127128129130131132133134135136137138139140141142143144145146147148149150151152153154155156

This is not what the challenge is expecting, so that's why it isn't letting you pass. Let me know if it still doesn't work for you when logging i inside the loop instead!
