need some help with this

Struggled with this, found an answer on line. But its saying task one is now failing (line 11).

What have i done wrong?

js/app.js 
//Problem: Hints are shown even when form is valid
//Solution: Hide and show them at appropriate times
var $password = $("#password");
var $confirmPassword = $("#confirm_password");
var $username = $("#username");

//Hide hints
$("form span").hide();

function isUsernamePresent() {
 if ($username.val().length > 0) {
    return true;
  }
}

function isPasswordValid() {
  return $password.val().length > 8;
}

function arePasswordsMatching() {
  return $password.val() === $confirmPassword.val();
}

function canSubmit() { return isPasswordValid() && arePasswordsMatching() && isUsernamePresent(); }
  return isPasswordValid() && arePasswordsMatching();
}

function passwordEvent(){
    //Find out if password is valid  
    if(isPasswordValid()) {
      //Hide hint if valid
      $password.next().hide();
    } else {
      //else show hint
      $password.next().show();
    }
}

function confirmPasswordEvent() {
  //Find out if password and confirmation match
  if(arePasswordsMatching()) {
    //Hide hint if match
    $confirmPassword.next().hide();
  } else {
    //else show hint 
    $confirmPassword.next().show();
  }
}

function enableSubmitEvent() {
  $("#submit").prop("disabled", !canSubmit());
}


function usernameEvent() {
  if(isUsernamePresent()) {
    $username.next().hide();
  } else {
    $username.next().show();
  } 
}

//When event happens on password input
$password.focus(passwordEvent).keyup(passwordEvent).keyup(confirmPasswordEvent).keyup(enableSubmitEvent);

//When event happens on confirmation input
$confirmPassword.focus(confirmPasswordEvent).keyup(confirmPasswordEvent).keyup(enableSubmitEvent);

$username.focus(usernameEvent).keyup(usernameEvent).keyup(enableSubmitEvent);

enableSubmitEvent();

Hi Samuel,

You have two return statements inside your "canSubmit" function.

Try this instead and it will work.

function canSubmit() {
  return isPasswordValid() && arePasswordsMatching() && isUsernamePresent();
}

Hey Samuel Thorpe,

You only need one return statement in the canSubmit() function. 

function canSubmit() { 
return isPasswordValid() && arePasswordsMatching() && isUsernamePresent(); 
}
