hi
i have a very complex form, with a section to add option and option values within it. the options section is generated by clicking a button. all this works.

so there can be an option like "color" and the values can be: red,green,blue.
and say "size" and the values can be : small,medium,large,xtra-large.

now i need to take the sum for EACH OPTION QUANTITY: lets say- the size option has 100 for small, 20 for large and so on.
i need the sum quantity for each option. so the sum of size will be 120.

i left the html as simple as i could to help you to help me, this is the html code:
        <div id="currentopts">
            <div class="optis" id="option158">
                <table class="optiontable">
                    <thead>
                        <tr>
                            <th>Option name</th>
                            <th>Position</th>
                            <th>Action</th>
                        </tr>
                    </thead>
                    <tbody>
                        <tr>
                            <td><input type="text" value="color" name="158" class="optclass"></td>
                            <td><input type="text" size="5" value="0" name="158" class="optpos"></td>
                            <td>

	var options = {};
	$('.optis').each(function() {
		var sum=0;
		var optionName = $(this).find('input[class="optclass"]').attr("value");
		$(this).find('input[name="quantity"]').each(function(){
			sum+=parseInt($(this).attr("value"));			
		});
		options[optionName] = sum;
	});

the options variable maps option name (color,size etc) and the sum of the quantities, so u ended up with:
options["color"] = 110
options["size"] = 120
options["sleeves"] = 140
