The trick will be to add the fields together. To do this, they all have to be of the same type. Since it looks like the result of this formula is a string, they'll all have to be converted to string. This can get tricky if any of your fields is a date, because the 'MM/dd/yyyy' won't sort correctly - you have to format it as 'yyyyMMdd'.
So you'll add a line that looks something like this:
case "Parameter Name" : {view.column1} & {view.column2}&ToText({view.datecolumn}, 'yyyyMMdd')
