Call to An Undefined Function Error

I have included the php file in my includes directory of my theme, but I still get this error when a function in that file is called:

Fatal error: Call to undefined function update_profile_show_error_messages() in /home/exlogu5/public_html/wp-content/themes/classroom/template-profile.php on line 23

This is the code where the function is called:
<?php update_profile_show_error_messages(); update_profile_show_sucess_messages(); ?>

And this is the function located in <mytheme>/includes folder:
function update_profile_show_error_messages() {
if($codes = update_profile_errors()->get_error_codes()) {
echo ‘<div class=”alert-danger form-message”>’;
// Loop error codes and display errors
foreach($codes as $code){
$message = update_profile_errors()->get_error_message($code);
echo ‘<span class=”error”>‘ . __(‘Error’) . ‘: ‘ . $message . ‘</span>
‘;
}
echo ‘</div>’;
}
}

I don’t have a general idea about why this error occurs and google didn’t help me so I appreciate any help! I cleared the cache thinking the file containing the code wasn’t updated, but the error still occurs.
