Как выбрать параметр в select по умолчанию?
Прикрутил к сайту выбор регион>>страна>>город следующим образом:

<?php
<script type='text/javascript' src='city_state.js'></script>
?>

<div id="widget">
Select region: <select onchange="set_country(this,country,city_state)" size="1" name="region">
<option value="" selected="selected">No matter</option>
<option value=""></option>
<script type="text/javascript">
setRegions(this);
</script>
</select>
Country: <select name="country" size="1" disabled="disabled" onchange="set_city_state(this,city_state)"></select>
City/State: <select name="city_state" size="1" disabled="disabled" onchange="print_city_state(country,this)"></select>
<div id="txtregion"></div>
<div id="txtplacename"></div>
</div>


city_state.js выглядит так:

var countries = Object();

countries['Africa'] = '|Algeria|Angola|Benin|Botswana|Burkina Faso|Burundi|Cameroon|Cape Verde|Central African Republic|Chad|Comoros|Congo, Dem.|Congo, Rep.|Djibouti|Egypt|Equatorial Guinea|Eritrea|Ethiopia|Gabon|Gambia|Ghana|Guinea|Guinea-Bissau|Kenya|Lesotho|Liberia|Libya|Madagascar|Malawi|Mali|Mauritania|Mauritius|Morocco|Mozambique|Namibia|Niger|Nigeria|Rwanda|Sao Tome/Principe|Senegal|Seychelles|Sierra

	else document.getElementById('txtplacename').innerHTML = country;
	}


Выбранные пользователем параметры записываю в базу:

$result5 = mysql_query("UPDATE users SET region='$region', country='$country', city_state='$city_state' WHERE email='$email'",$db);


достаю так:

$result2 = mysql_query("SELECT * FROM users WHERE email='$email'",$db);
$myrow2 = mysql_fetch_array($result2);
$reg = $myrow2['region'];
$coun = $myrow2['country'];
$city = $myrow2['city_state'];


ВОПРОС: как при загрузке формы, поумолчанию были выбраны регион, страна и город пользователя. Буду сильно благодарен за помощь ?
