I assume you're doing something like this:
sum("Sales") + above("Cumulative Sales")
If so, the problem you're seeing originates on the very first row. On the first row, there isn't any row above it. So above("Cumulative Sales") returns null. QlikView's standard is that if you add null to a value, the result is null. So your very first row is null. Since your very first row is null, row 2's above() will return null, and so on, until the entire table is nothing but null values.
There are several solutions, but my favorite is to use the rangesum() function. When you do a rangesum(), null values are treated as zero instead of null. That let's us do the addition we wanted to do. In other words, for the example above, you would use this expression for the Cumulative Sales:
rangesum(sum("Sales"),above("Cumulative Sales"))
If that's not the problem you're having, then I'll need more details.
, I need that it continue the clalculation until the very end!!!!!
