All div's are activated instead of one

All div's are activated instead of one

I have this code and it starts running when I load the page and when I click the link it opens an popup.
My popups are filled with an mail script. When the page is loaded all mails are send before I click on the link to show the popup.

  2.     $(document).ready(function() {
  3. //When you click on a link with class of poplight and the href starts with a # 
  4. $('a.poplight[href^=#]').live('click', function() {
  5.    var popID = $(this).attr('rel'); //Get Popup Name
  6.    var popURL = $(this).attr('href'); //Get Popup href to define size
  8.    //Pull Query & Variables from href URL
  9.    var query= popURL.split('?');
  10.    var dim= query[1].split('&');
  11.    var popWidth = dim[0].split('=')[1]; //Gets the first query string value
  13.    //Fade in the Popup and add close button
  14.    $('#' + popID).fadeIn().css({ 'width': Number( popWidth ) }).prepend('<a href="#" class="close"><img src="images/icon/delete.png" class="btn_close" title="<?php echo $lang['sluit'] ?>" /></a>');
  16.    //Define margin for center alignment (vertical   horizontal) - we add 80px to the height/width to accomodate for the padding  and border width defined in the css
  17.    var popMargTop = ($('#' + popID).height() + 80) / 2;
  18.    var popMargLeft = ($('#' + popID).width() + 80) / 2;
  20.    //Apply Margin to Popup
  21.    $('#' + popID).css({
  22.        'margin-top' : -popMargTop,
  23.        'margin-left' : -popMargLeft
  24.    });
  26.    //Fade in Background
  27.    $('body').append('<div id="fade"></div>'); //Add the fade layer to bottom of the body tag.
  28.    $('#fade').css({'filter' : 'alpha(opacity=80)'}).fadeIn(); //Fade in the fade layer - .css({'filter' : 'alpha(opacity=80)'}) is used to fix the IE Bug on fading transparencies 
  30.    return false;
  31. });
  33. //Close Popups and Fade Layer
  34. $('a.close, #fade').live('click', function() { //When clicking on the close or fade layer...
  35.    $('#fade , .popup_block').fadeOut(function() {
  36.        $('#fade, a.close').remove();  //fade them both out
  37.    });
  38.    return false;
  39. });
  40.     });

  2.     echo '<a href="#?w=100" rel="popup_bestelling_mail'.$row['best_id'].'" class="poplight" title="'.$lang['send'].'"><img align="center" src="images/icon/pdf_mail.png" /></a>';

  4.     <div id="popup_edit_bestelling<?php echo $row['best_id']; ?>" class="popup_block">
  5.     <iframe src="edit_bestelling.php?id=<?php echo $row['best_id']; ?>" frameborder="0" width="1000" height="575">
  6.     </iframe>
  7.     </div>
