/******************* File Comments **************************
Filename:		cscombo.js
Description:	This file populates comboboxes with all
	known countries (as of 03/26/2003).  When the user
	selects a country the state combobox will be populated
	with the states associated with the country selected.
Compatibility:
	MSIE 4, 5, 6
	Netscape 4.7, 6, 7
	WebTV
	Opera	
Usage:		I generally have this command executed just before
	the closing < / body > tag.  Also in the onChange event
	of the Country combobox.
Warnings:	There is a bug in IE that requires the focus to 
	be shifted any other control on the form or the defaults
	will be off by one.  There is a fix within the code however 
	if causes focus to be sent to either the country or state
	combobox.  Quick fix would be to add a *.focus();
	event to fire to a textbox on the form.

Example 1:
	...page...
	< SCRIPT >
		FillCountry(document.form1.Country, document.form1.State, 'USA');
		FillState(document.form1.Country, document.form1.State, 'Florida');
		document.form1.Title.focus();
	< / SCRIPT >
	< / body >
	< / html >
	...end...
Example 2:
	 onChange="FillState(document.form1.Country, document.form1.State, 'Florida')"

	Modified so that the whole contents work by passing the
	comboboxes to the function.  Also changed the coding so
	that it resides in a script include.  No longer requires
	minimal ASP.

	Modified to allow the passing of combo's instead of hard
	coding them.  Also created the default capabilities of
	passing a default country to be selected.

Example:  FillCountry(NameOfCountryCombo, NameOfStateCombo, DefaultCountry)
