I'm trying to create a new column in my existing index with a number type based on doc[''].value addition of total 4 columns, however, I'm not able to create a number based addition and create that new column using scripting fields (painless language) - Can someone please help?

I tried multiple code like below but, no luck in building this field named "totaltime"

```auto
    def totaltime = doc['responsetime'].value + doc['deliverytime'].value + doc['uiloadtime'].value + doc['uiapiloadtime'].value ;
    return totaltime;

```

Hi @prasad-jagtap,

Do you mind sharing the error that you get? Usually, they provide very good hints about what's breaking.
