Hey, Vladmir, if you still need help on this one, you create the $submit variable and set it = to select the $(".submit-btn"). then you call it and add the .attr() method to.

const $submit = $(".submit-btn"); $submit.attr("disabled", true);

For me, it required two different lines of code to pass. Natalie gave you part of the missing code, but then try cutting the first line in half. First declare the variable on one line, and then add the method on the second line. (Don't forget to insert semicolons.)

You're welcome. I hope you were able to pass.

try setting "disabled" to true:

const $submit = $('.submit-btn').attr('disabled', true);
