Post-tiles breaks smooth-slider

Hi,
Want to use post-tiles with smooth slider. Using the atahualpa theme. If I just have the smooth-slider it works fine. If I place post-tiles below the smooth slider on the same page, only post-tiles works and smooth-slider disappears. Disable post-tiles and smooth-slider reappears. If I place post-tiles before smooth-slider then smooth-slider is shown, however the text in the slider is messed up.

This is the code in my index.php that results in smooth-slider disappearing:

<?php if ( is_front_page() and (function_exists( ‘get_smooth_slider_category’ )) ) { get_smooth_slider_category(‘latest-news’); } ?>

<?php if ( is_front_page()) { echo do_shortcode(‘[post-tiles]’); } ?>

Interestingly, if I use the wp-tiles plugin instead of post-tiles (substituting the appropriate shortcode as above), smooth-slider works fine.

Any thoughts why this might happening. I’d really like to use post-tiles but need to have it appear below the smooth-slider on the home page.

Thanks for reviewing.

Pete
