I've been trying to get the example from the help files to work and I keep getting an error that my limited skill set cannot figure out.  Any thoughts?  I'm trying to sort a BOM table on a drawing that was created in 2011 but updated with 2012.

Here's the code from the example:

'This example shows how to sort bill of materials, hole, general, and weldment cut list tables.

'---------------------------------------------------------------------------
' Preconditions:
' 1. Open a drawing with one of the following tables:
'    * General
'    * Hole chart
'    * Weldment cut list
'    * Bill of materials parts-only table that
'      contains four columns: Item No, Part Number, Description, and Qty.
' 2. Click the move-table icon in the upper-left corner
'    of the table in the view.
'    The PropertyManager opens on the table.
' 3. If the table is a BOM table, ensure that
'    PropertyManager > Item Numbers > Follow assembly order is not selected.
'
' Postconditions:
' 1. Inspect the Immediate Window.
' 2. The tables are sorted as follows:
'    * If it is a BOM table:
'      * Primary sort is on column three (Qty).
'      * Secondary sort is on column one (Part Number).
'      * There is no tertiary sort.
'      * All column sorts are ascending.
'      * Rows are sorted into categories in the following order:
'          1. Parts
'          2. User-defined
'    * If it is a general table, the sort is descending on the first column.
'    * If it is a hole table, the sort is ascending on the Tag column.
'    * If it is a weldment cut list table, the sort is descending on the third
'      column.
