Crosstab query contains one or more invalid fixed column headings. (Error 3322)

The list of entries for a fixed column heading of a crosstab query (the PIVOT clause in a TRANSFORM statement) is not valid.

Possible causes:

• There are no entries in the list. There must be at least one value in the parentheses following the IN reserved word in the PIVOT clause.
• A blank entry appears in the list. Two commas in a row (,,) create a blank entry.
• The list contains a field name of more than 64 characters.

Correct the PIVOT clause and execute the query again.
