Answer 1

are you sure you want to select $("#res"+(d-1)+"a#p") ?
Im assuming that d is a number and you will therefore generate:
#res3a#p
in your selector, which is invalid, youre probably trying to do this
$("#res"+(d-1)+" a#p")

Answer 2

$("#btnOK").click(function(){
parent.$("#res"+(d)).load("Customise.php #uni", "PID="+$("#P option:selected").val());
parent.$.fancybox.close();
});
$("#res"+(d-1)+" a#p").fancybox({
'transitionIn' : 'elastic',
'transitionOut' : 'elastic',
'width':400,
'height':300,
'overlayOpacity' : 0.5,
'onClosed: function(){
$("#res"+(d-1)+" a#p").fancybox({
'transitionIn' : 'elastic',
'transitionOut' : 'elastic',
'width':400,
'height':300,
'overlayOpacity' : 0.5,
'type' : 'iframe'
});
},
'type' : 'iframe'
});
});
