    Exclamation Script from HTML form

    Hello,

    I am attempting to write a javascript function that calculates the cost of a trip for three different vehicles based on HTML form input (Please see HTML code below). Can you please take a look at my javascript function attempt (below) and provide any suggestions that you might have? Thank you.

    Code:
    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
         "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
      
      <head>
        <link rel="stylesheet" type="text/css" href="doc.css" />
        <!-- Alternate Netscape 4 shielding version of including css file
          <style type="text/css">@import "C:\Users\ME\Desktop\doc.css";</style>
        -->
        <script type="text/javascript" src="C:\Users\ME\Desktop\jsdoc.js">
        </script>
        <title>Calculating with JavaScript and HTML Forms</title>
      </head>
      <body>

        <p> In this lab lets look at some additional things that JavaScript
        can do, such as make calculations with user input from a form. </p>
        
        <h2>The Problem: </h2>
        
        <p>I want to take a drive from Colorado Springs to
        Yellowstone Park. The reported distance is 638 miles. I would like to know
        how much the fuel is going to cost me to make this round trip. I have three options
        for my transportation....Assume that gas costs on averate $2.33 per gallon.</p>
        
        <ol>
        	<li>My Car that gets on average 19mpg...</li>
        	<li>My Motorcycle that gets on average 76 mpg...</li>
        	<li>My Friends hybrid that gets on average 48mpg</li>
        </ol>
        <br />	
        
      <p>  Fill in the form items below to get the input necessary to make the calculations: </p>
        
       <p> <label>Distance to be traveled: <input type="text" size = "8" name="distance"
        id="dist" /></label></p>
       <p> <label>MPG for My Car: <input type="text" size = "8" name="mycarMpg"
        id="mycarMPG" /></label></p>
       <p> <label>MPG for Motorcycle: <input type="text" size = "8" name="mtrcycMpg"
        id="mcmpg" /></label></p>
       <p> <label>MPG for the Hybrid: <input type="text" size = "8" name="hybridMpg"
        id="hmpg" /></label></p>
        
        <div>
          <input type="button" value="Calculate the cost for each vehicle"
                 onclick="CalculateCost();"/>
        </div>
        
        <br /> <br />
        <table align="center" border="3">
        <tr>
        	<th>Cost with My Car</th>
        	<th>Cost with Motorcycle</th>
        	<th>Cost with Hybrid</th>
        </tr>
        <tr>
        	<td id="mycar">&nbsp</td>
        	<td id="mtrcyc">&nbsp</td>
        	<td id="hybrid">&nbsp</td>
        </tr>
        </table> 
        
      </body>
    </html>
    Code:
    function CalculateCost(){
    var dist = document.getElementById("dist").value;
    var mycarMpg = document.getElementById("mycarMpg").value;
    var mtrcycMPG = document.getElementById("mtrcycMpg").value;
    var hybridMpg = document.getElementById("hybridMpg").value;
    
    var mycar = document.getElementById("mycar").value;
    var mtrcyc = document.getElementById("mtrcyc").value;
    var hybrid = document.getElementById("hybrid").value;
    
    mycar = dist/mycarMpg*2.33;
    mycar = Math.round(mycar * 100)/100;
    
    mtrcyc = dist/mtrcycMPG*2.33;
    mtrcyc = Math.round(mtrcyc * 100)/100;
    
    hybrid = dist/hybridMpg*2.33;
    hybrid = Math.round(hybrid * 100)/100;
    }
