Currency drop down menu on product page?

I've got the currencies drop-down menu located in the header, which works perfectly fine but it seems that many customers couldn't see it. So, I've been trying to place it also somewhere next to the price on the product page (with the code indicated below) but when dropping it down to a different currency, that just takes me to the check-out page.

Could someone help me a bit?
Thanks!

<!-- Currencies -->

<?=zen_draw_form('currencies', zen_href_link(basename(ereg_replace('.php','', $PHP_SELF)), '', $request_type, false), 'get')?>

<?

    if (isset($currencies) && is_object($currencies)) {

      reset($currencies->currencies);
      $currencies_array = array();
      while (list($key, $value) = each($currencies->currencies)) {
        $currencies_array[] = array('id' => $key, 'text' => $value['title']);
      }

      $hidden_get_variables = '';
      reset($_GET);
      while (list($key, $value) = each($_GET)) {
        if ( ($key != 'currency') && ($key != zen_session_name()) && ($key != 'x') && ($key != 'y') ) {
          $hidden_get_variables .= zen_draw_hidden_field($key, $value);
        }
      }
    }

?>

        <?=zen_draw_pull_down_menu('currency', $currencies_array, $_SESSION['currency'], 'class="header1_sel" onchange="this.form.submit();"') . $hidden_get_variables . zen_hide_session_id()?>
</form>
<!-- End Currencies -->

If this is something too complicated to do, perhaps I should hire a developer for that job. What do you recommend?
