Hi @flamber. Thanks for responding. I'm trying to add a 3rd column to that table to show the % for each row and the "Share" expression is only calculating one value at a time and returning the results, e.g. I'd have to enter the following one at a time in the Summarize field:
Share([SchoolType] = "Alternative") * 100
Share([SchoolType] = "Elementary") * 100
How do I just enter one formula so it calculate a new column showing the % for each row?
