Update: Haim pointed out in the comments that I might have misinterpreted what you were after. So I'll present two options.

If you want to prevent the same values being selected:

$('table').delegate('select', 'change', function () {
    var other = $(this).closest('tr').find('select').not(this);
    if (other.val() == $(this).val()) {
        // Bad! Now what do you want to do?

        // Select nothing?
        this.selectedIndex = -1;
        // Make the row red?
        $(this).closest('tr').css('background-color', 'red');
        // Be reallllly annoying?
        alert('You have made a bad choice!');
    }
});

If you want to keep the two columns the same:

$('table').delegate('select', 'change', function () {
    $(this).closest('tr').find('select').not(this).val($(this).val());
});

i think he want to prevent this situation , not to have duplicate values, in your example you make this 2 select box same

@Haim, oh, that sounds very logical now that you mention it. Did not get that sense at all from the question though.

Box9, Thanks for the code. This code restrict in the next consecutive cell, what about to compare the entire table rows for any duplicates ?
