Sum of Custom Columns Using ColumnMapping

[JMWRetool]

This may be a rather simple question, but is there an easy way to the sum of a custom column using ColumnMapping. I've gotten close with actually pulling one of the cell's values across to the number input field, but I can't seem to identify and sum the remaining column's cells.

Any help would be greatly appreciated.

Hey @JMWRetool!

Can you try {{_.sum(Table_Advanced_selection.columnMappers['Custom Column 1'])}}? You can read more about the _.sum function here!

Amazing! It worked, thank you!
