Change the function to Min, Average, Sum or whatever the aggregate function needed.
You may work with a list of values with other separators than the "¶", just change this separator to match yours

|It's a small thing, but I added a case() statement to mine, to check if there's only one value (in which case any of the aggregate functions will fail).
Here's what mine looks like (sorry, I also changed the function and parameter names to better suit my needs...but you get the idea):
// AggregateValues ( Function; Values )
ValueCount(Values) <= 1; GetValue(values; 1);
Evaluate ( Function & " ( " & Substitute ( Values ; "¶";";" ) & " )" )
