??? If this example is in the tutorial, it is wrong. I most certainly didn't put it in there. There's no relation whatsoever between PREV(tot1) and tot. Anyway: If "average" is "total/time" then "total" is "average * time". No need for complicated PREV statements. -- __________________________________________________________________ / [EMAIL PROTECTED] [EMAIL PROTECTED] \ | work private | | My employer is capable of speaking therefore I speak only for myself | +----------------------------------------------------------------------+ | Technical questions sent directly to me will be nuked.
