FieldValue function bug

[avastani]

Has anyone come across a problem trying to use the FieldValue function in the formation

FieldValue('MyVariableExpressions', rowno())

where

LOAD * INLINE [

KPI, MyVariableExpressions

abc, $(veABC)

def, $(veDEF)

];

and, veABC = NUM(SUM({<MTDFlag=1>}Sales), '#,##.0') etc.

I am having the problem where the pivot table I use this in with KPI as the Dimension doesn't do as expected.

Any help would be appreciated.
