If the bookmark name looks like it could be a cell address, Word assumes it is a cell address.  In your example, Word is looking for a value in Column EQ, Row 2008 instead of the value contained in the bookmark named EQ2008.  To prevent this, make sure your bookmark name cannot be misinterpreted as a cell address.  Word will interpret a bookmark name as a cell address if the name begins with 1 or 2 letters followed by 1 to 5 numbers.
