Conditionals, field formatting and CustomPress

Hi,

I'd like my CustomPress fields to only display if content has been added. I'm using the following on incsub_wiki.php <?php echo do_shortcode('[ct id="ct_Yes_Point__text_dd31" property="title | description | value"]'); ?> can you tell me what code I'd need to wrap this in to make it work in the way I want?

Also, I see that CustomPress fields support HTML entry, is it possible to make it support BB Code also? And is there any way to make http://whatever.com turn into a link automatically?

Lastly, is there a way to make CustomPress fields support wpautop?

Thanks.
