为什么这个点击处理程序fadeToggle代码不起作用？

I am trying to fade in div elements but for some reason every time I preview my script code it just displays it and doesn't run it

my script code is -

 <script>
$("#t<?php echo $pNumber ?>").click(function() {
$("#b.<?php echo $pNumber ?>").fadeToggle("slow", "linear");
});
</script>

the PHP variable is used for changing div id's would this be causing a problem?

Thanks,

UPDATE -

example html this is for one of the div's (the id is incremented)

  <div id="t1">Carl Froch 'fitter than ever' for Andre Ward Showtime Super Six       fight</div>
  <div id="b1"><p>Carl Froch gives Andre Ward seven years but no encouragement to      believe their fight  on Saturday night is a war of the ages.</p><p>The 34-year-old WBC    champion from Nottingham rarely strays far from the 12-stone limit of his division and is     hard o...<p><a href=http://www.guardian.co.uk/sport/2011/dec/14/carl-froch-andre-  ward-showtime-super-six>Click here for full article</a></p>   </div  <script>
  $("#t1").click(function() {
  $("#b1").fadeToggle("slow", "linear");
  });
 </script>

In your element selectors:

• You're including the $pNumber as part of the t's id for the click event
• You're including the $pNumber as part of the b's class for the fadeToggle

To fix this, do one of these:

• Add a dot to the #t selector, to make it select based on class
• Remove the dot from the #b selector, to make it select based on id

See this fiddle before removing the .:

$("#t1").click(function() {
    $("#b.1").fadeToggle("slow", "linear");
});

See this fixed fiddle:

$("#t1").click(function() {
    $("#b1").fadeToggle("slow", "linear");
});
