Dynamic Update - duplicates count

[#1]

Hi guys,

I have used the dynamic update function, to dynamically update my periods into a table.

The value MAX_P is based on a variable vPeriod.

When I try to do a calculation alt(sum(if(Period = MAX_P, [Page Views]),0), my count gets duplicated...

I know this because when I pull a straight table per period, the sum of the page views are exactly duplicated.

Does anyone know why this could happen?

Thank you,

Lucille
