vHi, since my previous attempt to solve the Google Sheets problem was unsuccessful, I've created a simple scenario that illustrates my challenge. There is a Google sheet with sheets: DATA, X1, X2, ... Xn - In the sheet, DATA are variables - There is a SCRIPT node that calculates via JS simple multiplication - row by row - Result of multiplication of variables from each row has to be appended by the last node into a different sheet accordingly to X1, X2, to Xn Simple? When the scenario was executed, all the results were appended into sheet X1. Could you help me solve my puzzle ?
