Re: How can I limit the number of items being selected from parameter value dropdown list box?

Thank you Ludek. My problem is: the dropdown listbox must list all available values but only allow a user to pick any of the values up to 20. Can CR do that? I can change the number of values to be  populated in the dropdown list box (e.g., just list 20)  but  I must list all available values for users to pick and only no more than 20 values to be picked up. Thanks!
