Hi srinivaasant574373 This is the simplified version you can give a try,

a!localVariables(
  local!array1: {1,2,3,4},
  local!array2: {1,2,3},
  local!array3: {1,2},
  a!forEach(
    merge(local!array1,local!array2,local!array3),
    sum(fv!item)
  )
)

I use this complicated way to generate the local only to keep that nested list structure. You already have the data in that format.

As I understand it, there's no need to follow the definition of local!value. You can replace local!value with your own variable—the one on which you want to perform the calculation. You just need to copy this part accordingly. and it should work fine.

a!forEach(
    items: enumerate(count(a!flatten(local!value[1]))),
    expression: a!localVariables(
      local!outerIndex: fv!index,
      sum(
        a!forEach(
          items: enumerate(count(local!value)),
          expression: local!value[fv!index][local!outerIndex]
        )
      )
    )
  )

Hi Stefen,

The code is working for 2 elements. But in some scenarios I might have more than 2 elements based on length of array.

In the below scenario I have 4 elements in total, I have a local variable local!add containing all the elements.

I am trying the same code that you sent but the elements should not hardcoded.

local!length:length(local!add)
local!ss:{local!add[1]},
  local!ee:difference(local!add,local!ss),
  
  
  local!value:a!forEach(
    items: enumerate(local!length),
    expression:
    if(fv!index = 1, {local!ss}, {local!ee})
  ),
  local!ff:a!forEach(
    items: enumerate(count(a!flatten(local!value[1]))),
    expression: a!localVariables(
      local!outerIndex: fv!index,
      sum(
        a!forEach(
          items: enumerate(count(local!value)),
          expression: local!value[fv!index][local!outerIndex]
        )
      )
    )
  ),

Hi You can index each items in a local variable and perform addition in a!foreach. For example if you have two items you can follow this code->

a!localVariables(
  /*ignore below code (replicating ur array)*/
  local!a: { 0, 2,  },
  local!b: { 36, 82 },
  local!c: { 2, 8 },
  local!arr: merge(local!a, local!b, local!c),
  /*ignore above*/
  /*code for getting value in seprate varables*/
  local!arr1: index(local!arr, 1, ""),
  local!arr2: index(local!arr, 2, ""),
  /*addition*/
  local!arrayWithTheLessSize: if(
    length(local!arr1) <= length(local!arr2),
    local!arr1,
    local!arr2
  ),
  local!arrayWithTheMoreSize: if(
    length(local!arr1) > length(local!arr2),
    local!arr1,
    local!arr2
  ),
  a!forEach(
    items: local!arrayWithTheMoreSize,
    expression: fv!item + index(
      local!arrayWithTheLessSize,
      fv!index,
      0
    )
  )
)

one question, Can there be more than two items in that array?

You can try something like this! In your case the output is in local!a in the sample code below. you can ignore the other two variables local!x and local!y. Line 5 to 7 has actual solution.

a!localVariables(
local!x: { 0, 36, 2 },
local!y: { 2, 82, 8 },
local!a: a!foreach({ 1, 2 }, if(fv!item = 1, local!x, local!y)),
a!foreach(
local!a[1],
sum(fv!item, local!a[2][fv!index])
)
)

In my usecase I have both the arrays in a single local variable (local!final)

Like this

I need to perform the addition by iterating this local variable.

RE: Add elements in Array

Stefan Helzle — Mon, 26 May 2025 11:46:18 GMT

a!localVariables(
  local!values: a!forEach(
    items: enumerate(2),
    expression: if(fv!index = 1, {0,36,2}, {2,82,8})
  ),
  a!forEach(
    items: enumerate(count(a!flatten(local!values[1]))),
    expression: a!localVariables(
      local!outerIndex: fv!index,
      sum(
        a!forEach(
          items: enumerate(count(local!values)),
          expression: local!values[fv!index][local!outerIndex]
        )
      )
    )
  )
)

Hii srinivaasant574373 ,

Here is the solution which can cover you use case,

a!localVariables(
  local!a: { 0, 36, 2 },
  local!b: { 2, 82, 2 },
  local!arrayWithTheLessSize: if(
    length(local!a) <= length(local!b),
    local!a,
    local!b
  ),
  a!forEach(
    items: local!arrayWithTheLessSize,
    expression: fv!item + index(local!b, fv!index, null)
  )
)

Thanks

This output is stored in a local variable local!final

I just want to continue from here. I have a local variable with 2 items and I need to add the elements inside the array . I want the output as 2,118,10

I am trying a!foreach but can't able to achieve the logic

RE: Add elements in Array

sureshs276515 — Mon, 26 May 2025 11:14:20 GMT

a!localVariables(
local!first: { 1, 2, 3 },
local!sen: { 4, 5, 6 },
local!output: a!forEach(items: local!first, expression: fv!item) + a!forEach(items: local!sen, expression: fv!item),
local!output
)

Did you try a!foreach()?
