Answer 1

Your problem starts here

$("div#selection select.select option").each(function(){ if((this).val()==num){

change it to

$("div#selection select.select").each(function(){
if($(this).val()==num){

and all your problem solved. You might want to change the .each to .change if you are thinking of having the script triggered everytime the selection is changed.
