Hello, Trying to get the "Change Address button" to open in a small window to change the shipping address, then when at that change shipping address screen instead of the button to click continue I want the button to close that screen while saving the change and refresh the main screen (the cart)

working on this code to get it to open in a different window:
PHP Code:
<div class="buttonRow forward"><?php echo '<a href="' . $editShippingButtonLink . '"target="_blank">' . zen_image_button(BUTTON_IMAGE_CHANGE_ADDRESS, BUTTON_CHANGE_ADDRESS_ALT) . '</a>'; ?></div>
