Collapsible container containing shortcode

As you can see from the linked page, I’ve used the Easy accordion plugin to produce an accordion, but because shortcode doesn’t work inside the accordion I’ve had to add the download shortcode separately. Is there a possible solution suitable for a not very technical person (me!)?
Thanks
Carl
