Sum checkboxes and select options together

I am hoping to add the values of multiple select options and also checkboxes together using jQuery but have got a little stuck. My primary issue is that I receive NaN as my combined answer.

I initially just summed dropdowns which worked (an example can be found at http://pure.evolvedublin.com/phone) but now need to add checkboxes into the mix (as seen at http://pure.evolvedublin.com/broadband-phone).

When you click the Start button on both pages, the values become available.

I have tried using the solutions found in jQuery checkbox and select - sum the values and add in var and jQuery update initial price on click on checkbox that has data-price attribute but have not been able to get them working.

My jsfiddle with a sample of my code is here: http://jsfiddle.net/damienoneill2001/77Hhd/

I am using the following code to add the checkboxes, but just dont have it right:

jQuery('input:checkbox').change(function(){
    tot=0;
    jQuery('input:checkbox:checked').each(function(){
    tot+=parseFloat(jQuery(this).val());
});
tot+=parseFloat(document.getElementById("broadband_package").value)+parseFloat(document.getElementById("irish_mobile_package").value)+parseFloat(document.getElementById("intl_landline_package").value)+parseFloat(document.getElementById("intl_mob_package").value);
    jQuery('.cost-container').text(tot);
    jQuery('.cost-containerb').val(tot);
});

jQuery('.broad .irish_mob').change(function(){
    jQuery('input:checkbox').trigger('change');
});

The values should also only add to the total when the Add button is pressed.

Can anyone see where I am going wrong?

The following values return undefined when I first check something:

document.getElementById("intl_landline_package").value
document.getElementById("intl_mob_package").value

This is because these are divs, not selects, so value is undefined. You will need to loop through the checkboxes in these divs and add up their values individually.
