My alert is not working can someone spot my error?

function isFieldEmpty() { const field = document.querySelector('#info'); if (!field.value) { return true; } else { return false; } }

const fieldTest = isFieldEmpty();

if (fieldTest) { alert('Please provide your information.'); }

Make sure you remove the comment surrounding the '#info' div on the index file. Otherwise there is nothing for the querySelector to grab. Opening up the console should give you more information as to what's going on.

Hi Kendall McCall

Did you remove the value attribute from the input element?

If you didn't, then your condition will be false and you won't see the alert.
