    Chapter 10

    In the code blocks explaining how to use frame templates, the "Button2" button is written as anchoring to itself. I believe it should anchor to "Button1".

    As written on p. 172:

     <Button name="Button2" inherits="MyButtonTemplate">
     <Anchors>
         <Anchor point="TOPLEFT" relativePoint="TOPRIGHT" relativeTo="Button2" />
     </Anchors>
 </Button>

    The same error is present on p. 171.

    Chapter 11

    As written on p. 191 in Table 11-3.

    mana = UnitPower(unit[,powerType)

    The function is missing the closing bracket ].

    Thanks, John

    Chapter 22

    On p. 417, use of up, down, right and left in describing scrolling is inconsistent.

     /run ScrollFrameTest:SetHorizontalScroll(-50)
 /run ScrollFrameTest:SetVerticalScroll(50)

Note that the horizontal scroll requires a negative value to scroll the child to the right, whereas vertical scroll takes a positive number to scroll the child up.

    To be consistent with the caption for Figure 22-4 and the movement described, it should read, "the horizontal scroll requires a negative value to scroll the child to the left".

    The writing could also use some clarification. When the child is scrolling to the left within the scroll frame, the slider in the scroll bar is being moved to the right. This could be confusing.

    Thanks, these have both been added to the errata listings for those chapters.
