Hi All:

First, thank you to all of you.

Stefan: I had gone through the documentation that you linked to but the example there for 'interface' was for one-level. I tried to extrapolate from the other examples to interface and I kept getting errors messages of various kinds. I was looking to access nested CDT(?).

Peter: As for things I tried, I tried 'fv!row, fv!index, fv!items, '.fstcategory' and various combinations of that. I know that some of them weren't appropriate but I was throwing darts and hoping that one of them would hit. I didn't think of using 'RecordType' for the fstCategory because I didn't that was of the RecordType fstCategory. I guess, when I use relationship to extract data, I need to use RecordType.

Pragna: Your code did do what I was looking for - so, thanks.

Here was the original task that I was trying to do.

I was trying to use the lesson/tutorial example from Appian Learning Course on Web Integration to extract data from USDA food database and create two tables - one for the list of products and the other a list of nutrition information for each of the products - with gtinUpc as the key relating the two.

So, in the example below, I was trying to access the 'foodNutrients' elements but I don't know the 'record!Type' because that entire dictionary is the result from an API call to USDA Food Database. That is were I am stuck.

When I try .foodNutrients[1], I get the foodNutrients for gtinUpc"028749448709" - Ground Beef. However, I can not seem to access the individual nutrients like protein, etc.

Any help/hints would be appreciated.

Thank you.

value: fv!row[recordtype!record.relationship.field], which is fv!row[recordtype!FST Consolidated Product.fstCategory.CategoryName]. for best practice we use rich text field for display values. and null checks.

Agreed with Stefan - can you also provide some more context on what you have tried already? Generally you can index data from records or related records using the `recordType!` syntax and referencing the field or related field you want to use.

I think this should get you started.
