How can I recycle the values of urlBaseNova and apiKeyNova for the other items in the array? ![image](https://europe1.discourse-cdn.com/n8n/original/3X/8/a/8a24d57ec9c38ef61ccf665a4760b203b4f0a428.png) ---

Hey @Ruan17, I don’t know why, but for me when I run it with the expression like this, it runs perfectly {{ $node[“DADOS KUTT”].json[“urlBaseNova”] }} Then test and see if it works. ---

Seeing as your DADOS node has only one item output, and the node your referencing has multiple, the first item works, but the subsequent items 2-11 are looking for items 2-11 on the DADOS node which don’t exist (undefined). If your n8n version is new enough you can use the new magical item linking `$('DADOS KUTT').item.json.urlBaseNova` which should know that each of those 11 items in Set1 relate to item 1 in the DADOS node. The alternative, if the DADOS node will only ever output a single item is to use `$('DADOS KUTT').first().json.urlBaseNova`, or `$('DADOS KUTT').itemMatching(0).json.urlBaseNova`. The old version of this was `$item(0).$node['DADOS KUTT'].data.urlBaseNova` Check these specific docs - [Built in methods and variables reference - n8n Documentation](https://docs.n8n.io/code-examples/methods-variables-reference/#output-of-other-nodes) Here’s a sample workflow with each type of expression and the result ---

> [@pemontto](#): > > Here’s a sample workflow with each type of expression and the result It worked perfectly, thanks a lot for the help! Now how did you know how to use `{{ $('KUTT DATA').item.json.urlBaseNova }}` because I only knew how to use these two `{{ $node["DADOS KUTT"].json["urlBaseNova"] }}` and `{{ $node["KUTT DATA"].json.urlBaseNew }}` I want to know so I can study more ---

true🤣 I thought it was only for use in the `node code` hahaha and do you have any link to use the `node code`? ---

The documentation there applies to both the code node, and anywhere you can write an expression. One exception… the column that says `Available in Code node?` 😉 What I would recommend is doing the n8n courses, however I’m not sure they’ve been updated with the code node, and updated method/referencing… ---
