Help with PHP/Js in form

[Ion_Cannon]

Hello, i have a script that takes a billing address and a shipping address, it uses the following js to manage the country/states:

 

$(document).ready(function(){
$('select#id_country').change(function(){
	updateshipState();
});
updateshipState();
});

function updateshipState()
{
$('select#id_state option:not(:first-child)').remove();
	var states = shipcountries[$('select#id_country').val()];
	if( typeof(states) != 'undefined' )
	{
		for (indexState in states)
		{
			//ie bug fix
			if (indexState != 'indexOf')
				$('select#id_state').append('<option value="'+indexState+'"'+ (shipSelectedCountry == indexState ? ' selected="selected' : '') + '">'+states[indexState]+'</option>');
		}
		$('p.id_state:hidden').slideDown('slow');
	}
	else
		$('p.id_state').slideUp('fast');
}

 

and the script is called in php with the following:

 

<script type="text/javascript">
// <![CDATA[
idSelectedCountry = {if isset($smarty.post.id_state)}{$smarty.post.id_state|intval}{else}false{/if};
countries = new Array();
{foreach from=$countries item='country'}
{if isset($country.states)}
	countries[{$country.id_country|intval}] = new Array();
	{foreach from=$country.states item='state' name='states'}
		countries[{$country.id_country|intval}]['{$state.id_state|intval}'] = '{$state.name|escape:'htmlall':'UTF-8'}';
	{/foreach}
{/if}
{/foreach}

//]]>

</script>

 

The php form uses this to select:

 

<p class="required select">
			<label for="id_country">{l s='Country'}</label>
			<select name="id_country" id="id_country">
				<option value="">-</option>
				{foreach from=$shipcountries item=z}
				<option value="{$z.id_country}" {if ($smarty.post.id_country == $z.id_country)} selected="selected"{/if}>{$z.name|escape:'htmlall':'UTF-8'}</option>
				{/foreach}
			</select>
			<sup>*</sup>
		</p>

 

<p class="required id_state select">
			<label for="id_state">{l s='State'}</label>
			<select name="id_state" id="id_state">
				<option value="">-</option>
			</select>
			<sup>*</sup>
		</p>

 

My question is,  this works great for the billing address part of the form but I want it to do the same thing for the shipping fields but I cannot get it to work.  Would anyone have any ideas how I could make it work with my shipping section also on the same form?

 

thanks
