Roger,

Try DBA_EXTENTS instead. Something like below:

SELECT SUBSTR(TABLESPACE_NAME,1,16) "Tablespace",

  SUBSTR(OWNER,1,9) "Owner",  
  SUBSTR(SEGMENT_NAME,1,30) "Index",
  SUBSTR(sum(BLOCKS * 8),1,16) "Size K"

FROM DBA_EXTENTS
WHERE segment_type = 'INDEX'
Group By TABLESPACE_NAME, OWNER, SEGMENT_NAME ORDER BY 1, 2, 3; Jerry Whittle
