I am looking to create a % Mix calculation to create a line item to bring into one of my app pages. For example, I want to create a column next to 'Locked L52wk CY Vol' that shows the % for each MU of the Region (screenshot below). In the example below for MU - CO MT UT WY I would like to see that 133,729 is 35% of 380,896. Is there an easy way to do this?
