Dynamic Drop Down menus
 

I've built a php/mysql -based dynamic dropdown menu with the following code:

PHP Code:



However, the problem is that it returns all the records in the option tags.

For example if I'm building a dropdown menu on country, and there are three recordwith "USA" in the country field, it returns three options with the value of "USA". I only want it to return one for each unique value in the table.

How do I do that?
