jQuery Script Not working

[LimeX]

Hi!
I have a script that adds "?wmode=transparent" at the end of the src of every Youtube video in a div of #fp.
Here's what I got:

    var newsrc = $('#fp iframe').attr('src') + '?wmode=transparent';
    $('#fp iframe').attr('src', newsrc);

The problem with this code is that it targets the first iframe, takes the source of that and adds the source of the first video + ?wmode=transparent to all the other videos.
How do I rewrite the code so that it executes once for each iframe it finds?
I'm really new to jQuery and havn't been able to figure this out for a week.

$('#fp iframe').each(function(){
    var newsrc = $(this).attr('src') + '?wmode=transparent';
    $(this).attr('src', newsrc);
});

try that

It worked, Thankyou very much!
