Custom field with date HELP!

[chryslerclub]

Hello How are you?? I need your help in order to learn how to add a custom field in the registration form of VB 4.2.1 to insert a date e.g.: Wedding Date: m/d/YYYY

I try to add it in the cpanel options creating a new field but I couldn?t add a insert date field, just a one line or multi line ones are allowed.

could you please tell me how to do it??

Thank You Very Much

And i must apologise because my english is too poor...
