Nested ForEach and localVariable

Question

So, I am trying to capture and store nested data from USDA Database - API (image below) 
 
 Now I am trying to store this data in a record - fields being gtinUpc, number, name, amount, and unitName. I am trying to use the forEach-nested loop example from 
 https://docs.appian.com/suite/help/23.1/fnc_looping_a_foreach.html . 
 However, when I try to nest another forEach and iterate over the foodNutrients, I get errors. I have tried moving lines around - for example, move line 21 to outside the inner a!localVariables - nothing seems to work. 
 
 As always, any and all feedback/assistance would be appreciated. 
 Thanks

Hello Mana,

the ":" notation is just a declaration at the beginning of your form or expression rule to define your locals.
not assignend values later:

so here its lesse with the iteration lopping its with your ":" notation
Do you want to create a new record value set or update an existing one?

perhaps this one is helping you. So what I am saying: I see rather an issue how you create/update data IN your a!forEach than your a!foreach logic itself.

MaNa said: That variable is declared on line 30 - and is being given a value on line 42 
 To reiterate and simplify upon the prior correct responses by Stefan and Richard: this is not how local variables work. You need to set the value of the local variable where you declare it. Any use of a local variable needs to be done inside the same a!localVariables() statement in which it was declared. The code snippets you've posted here all violate both of these tenets.
