Use with advanced profile: I can't make it work

Hi there,

I am relatively new to Drupal 5.x and PHP but still manage to make most modules work and get by with some custom PHP coding. I want to use this module in order to make a custom field on the user registration form, using advanced profile. I want my custom field to validate the first name and last name fields to make sure they contain no illegal characters and are greater than 2 charcaters in length.

I have installed all the recommended modules (using nodeprofile not bio) and have read the installation documentation and the readme.txt provided. I can manage to create the field but can not get it to show up on user registration page with all of the other fields. When I look at the manage fields screen my field is there but the drop down box says hidden and this is the only option.

What am I missing? Any help will be greatly appreciated.

Thanks,
Mat
