Populating A Drop Down Menu?

Wonder if anyone can help. I have a page on my website where users can select their country and state/province from a drop down menu. The country and state/province drop down menus get populated from the mysql database using javascript: ie: the user select his country, and the states/provinces of that selected country is then populated into the drop down menu. The code looks like this:<select name="countryList" id="countryList" onChange="return CountryListOnChange()">So the js part onChange will only populate the states drop down menu when a new country is selected.Now the problem is: when the use goes back to his profile, he can see the country he selected, but not any state, since the states list is only populated onChange.
