                        Errata Type: Code Page No: 60

                        In the given table, the expression mentioned for the City dimension has a missing closing bracket ")".
                        It should be:
                        =Alt(
                           WildMatch(
                              GetFieldSelections(%Dimensions, '|'),
                              '*City*')
                        ,0)

                        Errata Type: Technical Errata Page: 121

                        In the example, Using RangeSum to calculate a rolling total in a multidimension table (chapter 4), the script has the dimensions "country, city, Sales and Orders", the first instruction is:
                        1. Create a new pivot table with year and country as dimensions.


                        It is suggested that you use the next script (page 123) for this example.

                        In the author's acknowledgment, the line: "None of what I do would be possible with them."

                        Should read "None of what I do would be possible without them."
