Okay, am I missing something? I wanted to use the Column Expressions mode to sum columns and use the results in other formula. I see ColMax, ColMin, Max, Min, Avg etc but no Sum? Is there really no summation function in Column Expressions Node?

An alternative is to use the Groupby node with manual aggregation(sum) on the columns you want to sum.

Hi @navywings, from what you said, I believe you wish to find the sum of a number of columns (rather than summing rows). I’m perhaps the one missing something, but why does this require a dedicated function? Why can’t you simply add the required columns together?

```
column("Column1") + column("Column2") + column("Column3") + column("Column4")
```

If @takbb assumption is correct then use column aggregator node. Col Expr is not always the best solution imho
