call from db stops validation working

[NightShift]

G'day everyone.

I have a registration page that has a state and country field.

If the country selected is Australia then a drop-list with Australian states is visable. If any other country is selected then a text field is visable.

This is all working through a javascript validation script and a static country drop list but when I change the country drop list to be populated from a MySQL list then it stops working and both fields are visable.

[See attached working file}

But if I change the "country_streetAddress" to pull the list from a MySQL database, it stops working and both boxes appear

<label>Country*:</label>
                <select name="countryField" id="country_streetAddress" style="width:110px;">
                  <?php
do {  

?>
                  <option value="<?php echo $row_countries['countryName']?>"<?php if (!(strcmp($row_countries['countryName'], "Australia"))) {echo "selected=\"selected\"";} ?>><?php echo $row_countries['countryName']?></option>
                  <?php
} while ($row_countries = mysql_fetch_assoc($countries));
  $rows = mysql_num_rows($countries);
  if($rows > 0) {
      mysql_data_seek($countries, 0);
	  $row_countries = mysql_fetch_assoc($countries);
  }
?>
                </select>

Thanks
