I am getting task 1 is no longer passing tryout having changed the code for task 1 at all. I have no Idea why

    </head>
    <body>

When using a for loop (in just about any language), you need to both declare & assign your iterator that's in the for loop. The problem with your code is, the variable x does not exist because it hasn't been declared anywhere before your for loop.

Example:

for(let x = 0; x < 9; x++){
  console.log(x);
}

I should probably have included that I am trying to loop through each paragraph element and make it blue. this is what I have tried

const section = document.querySelector('section'); const paragraphs = section.children; for (x=0; x < paragraphs.length; x++){ paragraphs[x].style.color = 'blue'; }
