Nodered Array Datenbank

[Saka Sakasitadi]

Hallo,
kann mir vielleicht jemand helfen?

Ich möchte mit dem Form-Node eine Menge und einen Artikel in die Datenbank schreiben. das funktioniert auch..

Mit dem Button soll die Datenbank ausgelesen und der Inhalt (Artikel, Menge) per mail gesendet werden.

Meine Lösung funktioniert, hat aber viele Nachteile. Ich muss eine genaue Anzahl an Variablen anlegen. Wenn die Anzahl der Variablen mit den Feldern der DB nicht übereinstimmt wird keine Mail gesendet.
Es muss einen einfacheren weg geben?! Ich komme aber nicht drauf.
