Hi guys,

I have a drop down box that allows the user to select the countries.

Code HTML4Strict:
<select size="1" name="D21">
 
<option>	Afghanistan	</option>
<option>	Aland Islands	</option>
<option>	Albania	</option>
<option>	Algeria	</option>
<option>	American Samoa	</option>
.
.
.
and etc....
 
		  </select>


How do I create a drop down box number 2, where If the user selects United States in drop down box 1, it will display all the states (e.g NY, LA...) for the user to select in drop down box 2

Is there any scripts online that does this ?
Thanks for the advice provided
