添加价格值以形成和计算

So I have looked around here and havent seen something that can help. Basically I have a form that works great. The form gets submitted to a review and from the review page you can send it off. What I am trying to do is get a "Price Total" on the review page. What I need to happen is add a value to sets of drop down items and multiply them to a the number of check boxes marked in a section. The link to the Fiddle will show what I am trying to do.

Example: how many Praxis PIs checked times their shaft selection.

<div id="leftDriver">
    <!-- Start Form -->
    <form action="reviewLeft.php" method="post" id="order">
        <!-- This is the club photos -->
        <div class="clubPhotos">
            <div class="club">
                <img src="clubs/img/praxispi.png" class="clubPhoto" /> <span class="clubTitle">Praxis PI</span>
 <span class="clubSub">Low Launch 9.5</span>

                <input type="checkbox" id="clubCheckbox4" class="clubCheckbox" name="DriverType" value="Praxis PI Low Launch 9.5" />
            </div>
            <div class="club">
                <img src="clubs/img/praxispi.png" class="clubPhoto" /> <span class="clubTitle">Praxis PI</span>
 <span class="clubSub">Mid-Low Launch 12.5</span>

                <input type="checkbox" id="clubCheckbox1" class="clubCheckbox" name="DriverType" value="Praxis PI Mid-Low Launch 12.5" />
            </div>
            <div class="club">
                <img src="clubs/img/praxispi.png" class="clubPhoto" /> <span class="clubTitle">Praxis PI</span>
 <span class="clubSub">Mid-High Launch 15.5</span>

                <input type="checkbox" id="clubCheckbox2" class="clubCheckbox" name="DriverType" value="Praxis PI Mid-High Launch 15.5" />
            </div>
            <div class="clear"></div>
        </div>
