Use the flex-grow Property to Expand Items #2

Could someone help me, I’m stuck in this challenge although I think I’m doing it right…
Does anyone have any idea what i maybe doing wrong?

Your code so far

  #box-container {
    display: flex;
    height: 500px;
  #box-1 {
    background-color: dodgerblue;
    height: 200px;
    felx-grow: 1;
  #box-2 {
    background-color: orangered;
    height: 200px;
    flex-grow: 2;

<div id="box-container">
  <div id="box-1"></div>
  <div id="box-2"></div>
