vSlider: Possibly a very simple php coding solution

vSlider – in WordPress I’m using the function supplied in the FAQs:

<?php if(function_exists('vslider')){ vslider('vslider_options'); } ?>

And I’m trying to do this. So its knows to get the post-ID as its name. But its not working.

<?php if(function_exists('vslider')){ vslider('<?php the_ID(); ?>'); } ?>

Any help is greatly appreciated, thanks.
