Crystal Report 11, list all values listed by user in the parameter fields

Hi

I created a crystal report, in that crystal report, there is a parameter field that requires the user to input contact nos. (not stored in the database). I've already set the parameter field to Can Grow and can insert multiple values, the problem is when I run the cystal report, it always displays the first parameter value inputed by the user.

How can i display all of the values inputted by the user.

Thanks in advance
