On Page 98, the proposed changes to `app.html.eex` include the following code:

```auto
    <a href="http://phoenixframework.org/" class="phx-logo">
        <img src="<%= Routes.static_url(@conn, "/images/phoenix.png") %>" alt="Phoenix Framework Logo"/>
    </a>

```

However, the compiler is complaining about the syntax and suggests the following:

```auto
    <a href="http://phoenixframework.org/" class="phx-logo">
      <img src={ Routes.static_url(@conn, "/images/phoenix.png") }
          alt="Phoenix Framework Logo"/>
    </a>

```

So basically the `<%=` element is not allowed within attribute values and braces should be used instead.

I guess this might be a change in how Phoenix Templates work added after the book was published?
