I am new to qlikview and I am working on a graph that or two variables. The data for one variable is a lot larger than the other so I am trying to standardize my variables to either [-1, 1] or [0,1] based on criteria selected in two different list boxes; one for year and other other for region.
without seeing the real data it might be a bit complicated to judge on possible spelling-errors etc.
But would suggest to analyse your formula term-by-term.
It may also help, not to assign a lable to your expression in a (straight)table. on mouse over you may see, which values are used in your expression. This may assist you in finding the error (pay special attention to NULL-values then)
