In app.js, on line 119:

        if (select) {                           // old: this only checks that "select" exists
        if (select.value != "Not Responded") {  // fix: this checks if a response was selected

And before assuming that the change event was triggered by the select, you should check the tag like you do for "BUTTON" on line 127.

Thank you, updated the handler

``` ul.addEventListener('change', (e) => { if ( e.target.tagName === 'SELECT') { const select = e.target; const listItem = select.parentNode;

    if (select.value != 'Not Responded') {
        listItem.className = 'responded';
    } else {
        listItem.className = '';
    }
}
}); ```
