How to avoid creating multiple variables that perform the same calculation logic?

Syntax
#1

Hello Survey Solutions Team.

I would like to know how I can avoid creating multiple variables that perform exactly the same operation but in different sections.

For example, I have a form with 22 sections (see the imagen)

The variable have the operation aritmethic MainVariable:
RosterSections.Select(x=> (x.ProductValue??0) - (x.HelpReceived??0)).ToArray()[@rowcode-1]

The last explication create an array like this:
[ValueSection1, ValueSection2, ValueSection3, ValueSection4,...,ValueSection22]

But if I want to access at the value of each section I should to create each variable for each item in the array.
Like this way
ValueInSection1 = RosterSections.Select(x=> x.MainVariable).ToArray()[0] ValueInSection2 = RosterSections.Select(x=> x.MainVariable).ToArray()[1] . . . ValueInSection22 = RosterSections.Select(x=> x.MainVariable).ToArray()[21]

But I would like to know an optimal and more efficient way to do this.

Thanks for help me.

Hello Kevin,

my sense is that you wish to display them as separate values in the screen report/summary section. Hence they must be calculated and stored as separate variables, that would be later accessible in text substitution %varname%.

You could probably simplify the notation with a macro:

ValueInSection22 = $sections[21]

where $sections is defined as:

RosterSections.Select(x=> x.MainVariable).ToArray()

This will reduce the possibility of a typo and will ease subsequent transformations, but wont give any computational gain.

Best, Sergiy

Hello Sergiy

Exactly that is my intention, display them as separate values.

Fantastic, yesterday I built a macro like this, each section stores its value in a specific position of the array.

Thanks Sergiy, your help is very valuable in our project
