You are a godsend thank you so much this worked perfectly. I dont think I ever connected that the problems was mismatching types

The type of the choice values & the Value is different

typename(typeof(local!pubProd[1])) --> using this you can confirm the data types is different(use this for future findings)

the choice values - integer type (but)

local!dataProd1[fv!index] is returning text type

So cast() both choice values and the value as same datatype or in simple you can try this tointeger(local!dataProd1[fv!index])

How would you recommend I implement this?

Hi,

Try the updatearray() function to update the specific index value in an array,

updatearray() Function - Appian 21.4

updatearray( array, index, value ) for the index if you use the wherecontains() fn - which will help you to locate the index for the given value to update

Update:

If I predefine it like this:

  local!pubProd: repeat(4, null),
  local!dataProd1: repeat(4, null),

it works well except for the error I get which is:

Could not display interface. Please check definition and inputs. Interface Definition: Expression evaluation error at function a!forEach [line 9]: Error in a!forEach() expression during iteration 1: Expression evaluation error at function a!dropdownField [line 16]: A dropdown component [label="Producing Organization"] has an invalid value for "value". All selected values must be present in the choiceValues array, but value was 1 and choiceValues was 1; 2; 3; 4; 5; 6; 7; 8; 9; 10; 11; 12.

I am not too sure where I would put the a!update function. I tried putting it in the saveInto but that doesnt seem to work how I want it too.

Have you tried using the a!update() function within saveInto? Here is the documentation link for it
