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.
