Hi
I would like to concatenate 2 columns, cat3/cat4, but if there is no value in the second column (cat4) than I would like to have no value in the added column
I’ve tried the aggregator with string manipulation but I don’t have the result I want.
hi cinthy
i’m using the expression node to implement the following logic:
“If there is no value in the second column (cat4), then I want the added column to have no value.”

I’ve tried to use the formula but there seems to be something wrong.
When I evaluate I get an error.
