Create Category

Hello! I'm looking for some advice, in creating categories, but I'm using a logic statement like this: IF [Content Category] = "Content" then "Content" ELSE [domain] END

Where "Content" it's a value in my column1 but [domain] it's a column2. If the value in column1 is "Content", then use "Content", but, if it's different from "Content", use the value in the [domain] column.

Thanks in advance for your help!
