Chapter 8: Page 148 - 'Anchoring Objects'

In the example given at the top of page 148, it should read as follows:

<Frame name="MyFrame1" parent="UIParent">
  <Size x="50" y="50"/>
  <Anchors>
    <Anchor point="CENTER" relativePoint="CENTER"/>
  </Anchors>
</Frame>
<Frame name="MyFrame2" parent="UIParent">
  <Size x="50" y="50"/>
  <Anchors>
    <Anchor point="TOPLEFT" relativePoint="TOPRIGHT" relativeTo="MyFrame1"/>
  </Anchors>
</Frame>

The errors are the missing 's' at the end of the Anchors tags, and a missing 1 at the end of MyFrame1 in the anchor for the second frame.
