Move the var aPrice to the top level of the script block.  By defining it
within the function, you are making it local.  As soon as the function is
ended, the variable become vapor.  So, you should have something like:

  <script type="text/javascript">    var aPrice;
    function pRec(size, material, price) {
      this.size = size
      this.material = material
      this.price = price
    }
    function makeItSo() {
      aPrice = new Array(24);
      aPrice[0] = new pRec("10 x 12",".024 Alumnium","9.35");      ...
      aPrice[24] = new pRec("7 x 10",".060 Polystyrene","4.4");
    }
    window.onload = makeItSo();
  </script>
