Hi Travis,
Your question is confusing and/or details will help us to help you better. We understand that you've 35+ people with Last Name = "Auger".
Question: Are all those 35+ values coming from one object in the universe (column in the database)?
If your answer is No, meaning those values are coming from different objects in Universe (columns in database), then, we'll need to more details like sample data, what objects do you have in the universe and what do you want to achieve.
If your answer is Yes, meaning those values are coming from one object in universe (column in database), then, the sample formula you have is inconsistent with what you're saying, "Auger is someone's last name, I have about 35 of these names and instead of creating them all individually, I would like to make this one dimension and include everyone."
Are you trying to create a variable with a logic that includes 35+ objects?
In your formula, what is [Lead ISM], [BP ISM], [BP ISM-2]?
Thanks,
