When you say "script", it makes me think of when you are initially loading the data into QlikView. The advice I gave is used in the chart design stage.
If I understand what you are saying, and you are designing a chart, then put all of those expressions into the hidden column I mentioned in the third part of my previous post. I think something like the following would be helpful:
IsNull(Expr1) = 0 AND IsNull(Expr2) = 0 AND IsNull(Expr3) = 0 ...etc.,
The suppress missing on the Presentation makes the chart suppress values where the expression has a missing value. But you want to do it where the dimension has a missing (Null) value. You should set this on Chart properties -> Dimensions -> Suppress when value is Null.
