In the HTML for the select tags you have used two id's namely "day1" and "wd1". id is a unique feature of a particular tag.So u can change it with a single id.

i have made the following changes to the HTML page :DAY 1: <select id="day1" title="- Select day -" name="day1" tabindex="14" > <option selected>-select-</option> <option value="1">Sunday</option> <option value="2">Monday</option> <option value="3">Tuesday</option> <option value="4">Wednesday</option> <option value="5">Thursday</option> <option value="6">Friday</option> <option value="7">Saturday</option> </select>.

so we may refer to the select id "day1" and write a on change function for the necessary validations.

Javascript code:

$(document).ready(function(){
$("#day1").on('change',function() {

  var index = $('#day1').get(0).selectedIndex;
  alert(index+"index");

  $('#day2 option:eq(' + index + ')').attr("disabled","disabled");
  $('#day3 option:eq(' + index + ')').attr("disabled","disabled");

});

});

where "day2" and "day3" corresponds to the id of the below select fields with days.

Similarly same approach can be dealt with time too.
