Loading Value of Input into Slider Options
<p>I need the variable "value" in my slider plugin to be the integer value of a input in the form:</p>

<pre><code>$(function () {
  $("#calcSlider").slider({ 
    min: 0,
    max: 90,
    step: 5,
    value: /* ACCESS HERE!!!!!! */,
    slide: function (event, ui) {
      $("#calcSup").val(ui.value);
    }
  });
});
</code></pre>

<p>I need <code>value:</code> to be the value in <code>calcSup</code> or <code>${form.calcSup}</code>, but that is a string. I need it parsed to a int:</p>

<pre><code>&lt;input type="text" 
       id="calcSup" 
       name="calcSup" 
       value="${form.calcSup}" 
       size="3" 
       readonly="readonly" /&gt;  
</code></pre>
