<div class="layout-slider">
<input id="CPUslider" type="slider" name="price" value="1" /></br>
<input id="RAMslider" type="slider" name="price" value="1" /></br>
<input id="HDDslider" type="slider" name="price" value="1" />
</div>
<script type="text/javascript">
var vdscpu = 0;
var vdsram = 0;
var vdshdd = 0;
jQuery("#CPUslider").slider({ from: 1, to: 20, step: 1, round: 1, scale: [1, '|', 5, '|' , '10', '|', 15, '|', 20], skin: "round_plastic",
onstatechange: function( value ){
vdscpu = value}
});
jQuery("#RAMslider").slider({ from: 1, to: 16, step: 1, round: 1, scale: [1, '|', 4, '|' , '8', '|', 12, '|', 16], skin: "round_plastic",
onstatechange: function( value ){
vdsram = value}
});
jQuery("#HDDslider").slider({ from: 1, to: 100, step: 1, round: 1, scale: [1, '|', 10, '|' , 20, '|', 30, '|', 40, '|', '50', '|', 60, '|', 70, '|', 80, '|', 90, '|', 100], skin: "round_plastic",

</script>
<div>Общая цена</div>
<div id="totalprice"></div>
<script type="text/javascript">
var vdscpuprice = vdscpu;
