I am trying to add "Gender" as a new profile that the user must enter when registering.  I want to have a drop down menu from which the user can chose between male or female.  My problem is that I don't know how to make that list thing work.

Specifically, I created a new profile with the property name called gender.  Then for its data type, I choose "list" (and a drop down list was indeed created).  However, there is no place for me to populate/edit the actual list to add in the choices "male" and "female" (and because of that, the drop down menu is empty).  Can someone tell me how to populate that list (drop down menu)?  thanks.

Thank you.
