An "if" statement

[ideasgirl]

Hello my php nerdy friends, can someone tell me how do I change this code to make it to show up ONLY when there's a review present:

<?php 
  echo '<p class="reviewCount">';
  if ($flag_show_product_info_reviews_count == 1) {
    echo TEXT_CURRENT_REVIEWS . ' <strong>' . $reviews->fields['count'] . '</strong><br />';
    $stars_image_suffix = str_replace('.', '_', zen_round($reviews_average_rating->fields['average_rating'] * 2, 0) / 2); // for stars_0_5.gif, stars_1.gif, stars_1_5.gif etc.
    $average_rating = zen_round($reviews_average_rating->fields['average_rating'], 2);
    echo TEXT_CURRENT_REVIEWS_RATING . ' <strong>' . $average_rating . '</strong> ' . zen_image(DIR_WS_TEMPLATE_IMAGES . 'stars_' . $stars_image_suffix . '.gif', sprintf(BOX_REVIEWS_TEXT_OF_5_STARS, $average_rating));
  } else {
    echo '';
  }
  echo '</p>';

I know I have to insert something like:

if ($reviews->fields['count'] > 0 ) { ?>

I just don't know where and how exactly.

Thanks in advance!
