Above() Not Working in Straight Table

[asmithids]

Hello,

Attached is a qvw containing a straight table with a simple SalesQTY expression.  I need to show a rolling number as sales transactions are posted.  I am using the following calculation to accumulate the sales down the column, but it is not working.  Can someone please offer assistance.  I've checked the community and by all accounts the Above() function should work.  Thank you!

SalesQTY+Above(SalesQTY)
