Hi Agnes,

There are a few issues with your code:

  1. You are getting a parse error because you have =< instead of <= (note it looks the way you say it: "less than or equal to"
  2. You only want to increment by one each time through the loop, so that you hit every number between 4 and 156.
  3. You are only logging the string 'value', and not an actual number. You need to use the same variable you have in your for loop - i.
  4. There's no need to use a variable named 'value' outside your for loop.

Here's the solution:

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