Crystal Reports : The "automagical" Multi-Element Parameter

When using a parameter that accepts multiple values, you will notice that you can't just drag it onto the report. We must pass it to the "Join" Crystal Function to "split" the values out.

Our parameter field is called {?UserID}, and accepts multiple values.

Create a formula with the following code:

Join({?UserID}, ", ")

This will return all UserID values within the {?UserID} parameter, separated by commas.
