Formulas with Date Ranges

Hey there!

Im testing out some workflows and am trying to run a formula on a date-range column. Specifically, I am trying to pull out the End Date value in a date-range, so I can run further date methods on it

I read in some documentation that I can use Max() in order to grab the end value which makes sense, but am getting an error when I do so.

The formula I am running that is giving me an error is simply (what am I doing wrong)?
