Learn Form Validation by Building a Calorie Counter - Step 38

Tell us what’s happening:

I am stuck on this challenge. Someone can help me?

Your code so far

function addEntry() {
const targetId = ‘#’ + entryDropdown.value;
const targetInputContainer = document.querySelector();
concat(targetId + ’ input-container’);


The challenge seed code and/or your solution exceeded the maximum length we can port over from the challenge.

You will need to take an additional step here so the code you wrote presents in an easy to read format.

Please copy/paste all the editor code showing in the challenge from where you just linked.

Replace these two sentences with your copied code.
Please leave the ``` line above and the ``` line below,
because they allow your code to properly format in the post.

I know the instructions say “concatenate ”, but they only mean to use the “+” operator. Also, I suggest you use Google to see how document.querySelector() operates (from w3 schools or MDN reference).
