Grazie mille per questo!
Il campo profilo utente personalizzato che sto cercando di utilizzare è ‘NZRAB number’
Ho provato, con lo script risultante qui sotto, ma ovviamente l’ho sbagliato, poiché questo ha generato l’errore ‘Undefined function’
Non ero sicuro se il nome del campo dovesse escludere lettere maiuscole o spazi - l’Editor non sembrava gradire almeno lo spazio nel nome del campo, quindi ho sostituito con un underscore
Potrei anche stare confondendo il nome del campo con l’etichetta del campo - ma se è così, non sono sicuro di come capire quale nome del campo corrisponde all’etichetta ‘NZRAB number’

Se da questo hai dedotto che non ho la minima idea di cosa stia facendo, avresti ragione!
