Why is this facebook app refreshing endlessly - php

Question

I kindly request that you help me identify the reason in the code why my app keeps refreshing endlessly. This does not allow me to navigate to other pages, Iam a learner in php and I suspect this could be the issue, help. Could it be a problem with the php arrangement?
Here is the code in index.php
<script type="text/javascript">
$(document).ready(function() {
$('#premium_b').click(function(e) {
e.preventDefault();
$('#tabs').tabs( "select" , 4 );
});
$('#tabs').bind('tabsselect', function(event, ui) {
if (ui.index == 4 )
$('#premium_b').css ('display', 'none');
else
$('#premium_b').css ('display', 'block');
});
});
</script>
<div id="bloc_134" class="li_bloc"><ul class="menu"><li>Home

Well, I see 3 times:
top.location.href=....
without any condition and not in a function call. That would certainly keep your page jumping.
