Thanks for helping me out with this... I couldn't find a contactus.tpl - when I checked where the "Contact Us" link points to it was this:

{$lng.lbl_contact_us}

So this is the code from "include/help.php":

if ( !defined('XCART_SESSION_START') ) { header("Location: ../"); die("Access denied"); }

$location[] = array(func_get_langvar_by_name("lbl_help_zone"), "help.php");

if (!empty($login))
	$userinfo = func_userinfo($login,$login_type);

if (empty($section)) $section = "";

if($action=="contactus" || $section == 'contactus') {
	$additional_fields = func_get_add_contact_fields($current_area, $login);

	$default_fields = unserialize($config["Contact_Us"]["contact_us_fields"]);
	if(!$default_fields) {
		$default_fields = array();
		foreach($default_contact_us_fields as $k => $v) {
			$default_fields[$k]["title"] = func_get_default_field($k);
			$default_fields[$k]['avail'] = (is_array($v['avail'])?$v['avail'][$current_area]:$v['avail']);
			$default_fields[$k]['required'] = (is_array($v['required'])?$v['required'][$current_area]:$v['required']);
		}
	} else {
		$tmp = array();
		foreach($default_fields as $k => $v) {
			$tmp[$v['field']] = array("avail" => (preg_match("/$current_area/S", $v['avail'])?"Y":""), "required" =>(preg_match("/$current_area/S", $v['required'])?"Y":""), "title" => func_get_default_field($v['field']));
		}
		$default_fields = $tmp;
		unset($tmp);
	}
}

if ($REQUEST_METHOD=="POST" and $action=="contactus") {
#
# Send mail to support
#
	$HTTP_POST_VARS["body"] = stripslashes($HTTP_POST_VARS["body"]);

	while (list($key,$val) = each($HTTP_POST_VARS))
		if($key != 'additional_values')
			$contact[$key]=$val;

	$fillerror = false;
	foreach($default_fields as $k => $v) {
		if(empty($contact[$k]) && $v['required'] == 'Y' &&  $v['avail'] == 'Y') {
			$fillerror = true;
		}
	}
	if(!$fillerror and is_array($additional_fields)) {
		foreach($additional_fields as $k => $v) {
			$additional_fields[$k]['value'] = $HTTP_POST_VARS['additional_values'][$v['fieldid']];
			if(empty($HTTP_POST_VARS['additional_values'][$v['fieldid']]) && $v['required'] == 'Y' &&  $v['avail'] == 'Y')
				$fillerror = true;
		}
	}

	if(!$fillerror) {
		$fillerror = (empty($subject) || empty($body));
	}
	if(!$fillerror) {
		$contact["b_statename"]= func_get_state($contact["b_state"], $contact["b_country"]);
		$contact["b_countryname"]= func_get_country($contact["b_country"]);
		if ($config["General"]["use_counties"] == "Y")
			$contact["b_countyname"]= func_get_county($contact["b_county"]);

		if(!empty($active_modules['SnS_connector']) && $current_area == 'C') 
			func_generate_sns_action("FillContactForm");

		$mail_smarty->assign("contact",$contact);
		$mail_smarty->assign("additional_fields",$additional_fields);

		func_send_mail($config["Company"]["support_department"], "mail/help_contactus_subj.tpl", "mail/help_contactus.tpl", $contact["email"], true);

		func_header_location("help.php?section=contactus");
	} else {
		unset($HTTP_POST_VARS['additional_values']);
		$userinfo = $HTTP_POST_VARS;
		$userinfo["login"] = $userinfo["uname"];
	}
}
#
# Recover password

$accounts = func_query("select login, password, usertype from $sql_tbl[customers] where email='$email' and status='Y'");

# Decrypt passwords

if($accounts) {
	foreach($accounts as $key=>$account)
		$accounts[$key]["password"]=text_decrypt($accounts[$key]["password"]);

        $mail_smarty->assign("accounts",$accounts);

        func_send_mail($email, "mail/password_recover_subj.tpl", "mail/password_recover.tpl", $config["Company"]["support_department"], false);

        func_header_location("help.php?section=Password_Recovery_message&email=".urlencode($email));

else
        func_header_location("help.php?section=Password_Recovery_error&email=".urlencode($email));

}

if ($section=="contactus") {

	include $xcart_dir."/include/countries.php";
	if ($config["General"]["use_counties"] == "Y")

if($section == 'cvv2') {
	$popup_title = 'What is CVV2?';
}

if($popup_title)
	$smarty->assign("popup_title", $popup_title);

}

$smarty->assign("userinfo",@$userinfo);
$smarty->assign("fillerror",@$fillerror);

$smarty->assign("additional_fields", $additional_fields);

$smarty->assign("main","help");

?>

Hope that makes sense - thanks again!!
