javascript converter
<p>I am having trouble finishing this javascript to convert coffee prices..I downloaded a debugger and it keeps telling me that price is undefined and i dont understand..here is the script..</p>

<pre><code>&lt;html&gt;
  &lt;head&gt;
    &lt;title&gt;Coffee House&lt;/title&gt;
  &lt;/head&gt;
  &lt;body&gt;
    &lt;script type="text/javascript"&gt;
      var drink, ounces, price;

      prompt ( "Enter the drink type: espresso, latte, cappuccino, americano" );
      prompt ( "Enter the oz: 8, 12, 16" )

      var shots = prompt ( "Enter the number of shots" )

      if ( drink == "espresso")
        price = 1.40;

      if (( drink == "latte") || (drink == "cappuccino" )) {
        if ( ounce == 8 )
          price = 1.95;
        else if ( ounce == 12 )
          price = 2.35;
        else if ( ounce == 16 )
          price = 2.75;
      }

      if ( drink == "americano" )
        price = 1.20 + ( ( (ounce -8)/8 ) * .30 );

      price = price + ( (shots) * .50 );
      price = "price" * 1.055;
      price = Math.round( price * 100 )/100;
      alert( "Your " + ounce + "oz. " + drink + "with " + shots + "shots of espresso costs: $ " +price );
    &lt;/script&gt;
  &lt;/body&gt;
&lt;/html&gt; 
</code></pre>
