Diagnosis
You attempted to define a query where the line width of the generatedlist is greater than 255 characters.
You define the line width on the Title, Format screen whichpermits a maximum width of 255 characters. However, when definingstatistics and ranked lists, you can implicitly increase this value,since the lines cannot be broken up. This is the case here. An implicitincrease in the width of the list would result in a list wider than 255characters. For this reason, the query cannot be executed.

Procedure
Check which of the statistics or ranked lists is responsible and modifyit so that the resulting list width is no greater than 255 characters.
