First, in Settings Form, go to Custom JavaScript field:
JavaScript code:
function setNomeCompletoValue(value){
NWF$('#'+NomeCompleto).val(value);
}function setDataNascimentoValue(value){
NWF$('#'+DataNascimento).val(value);
} function setNomePropriedadeValue(value){
NWF$('#'+NomePropriedade).val(value);
}
If(lookup("Partners_Database_v2", "Customer",DatabaseCodSAPCliente , "Customer")>1,"Registration Found", If(DatabaseCodSAPCliente==0,"","Registration not found, please contact the Analyst in your region"))
setNomeCompletoValue(lookup("Partners_Database_v2", "Customer",DatabaseCodSAPCliente , "Full Name"));
Partners_Database_v2 is a second list that is used as a database, where it will be the reference of the Lookup formula.
After this, your Single Line Textbox will be able to autopopulate the fields as needed.
