Barcode scan & popupRecord

Hello,

this topic has been widely discussed but even so I'm stuck trying to use popupRecord when a barcode is scanned.

I have two tables 'Articles' and 'Exist' the second is a weekly inventory table where I inserted a button to scan a barcode and open the article with the same number as scaned. I'm trying with the following code on the button:

let code := barcodeScan();
barcode := code;
popupRecord(record(Artigos,number(Artigos.'Código Barras' like barcode)))
