Expression with variables and function

[giovanni_scalzo]

Good morning, I'm new of QlikView and I would know the meaning of thid expression that I can understand.

I would add a value for the Measures that are created with this expression but I can't.

=replace (if (vShowVolumes, _Measure, aggr (only ({<_Measure = - {'Volumes','Share On Selections','% On Total'} >} _Measure), _Measure)), 'Transaction', vIncentiveNavigatorType)

Someone can help me ?

Thanks a lot !!!
