Hi all,

I would like to modify register.php as follows:

- Add a drop down field.
- Add a text field

- Add a radio button with two options:

If option 1 is selected, the drop down field is enabled and the text field is grayed out.

If option 2 is selected, the drop down field is disabled and the text field is enabled.

If this was an HTML site, I could do this easily in Javascript, but I do not know PHP at all. Can anyone pleaaase help? I am using version 2.0.16.

Thanks.

P.S. I could use one of the existing text fields for my purpose instead of adding a new one.
