Ahh, this is a common mistake on this step. Changing the text of an element means to change the text inside of the element, in other words, between the opening and closing tags. In this case the opening tag is <h1> and the closing tag is </h1>. So you want to change that text that is in between those two tags.
You might want to restart the step to get the original HTML back and then just change the text between those two tags.
