Bug in valid code. Undefined function error.

Undefined returned on valid code?

I believe this is a bug.

"var fullName = document.getElementByID("full_name");" should not return as undefined.

var fullName = document.getElementByID("full_name");
var lastName;
<!DOCTYPE html>
<h1 id="full_name"><span class="first_name">Andrew</span> <span class="last_name">Chalkley</span></h1>

<script src="app.js"></script>

you have last "D" capitalized in .getElementById...it should be lowercase.

Thank you sir! You are a saint and a scholar.
