You can organize your form information to help users to fill it out in a certain order, you do this with the <legend> and <fieldset> tags.
Legends
ex.
  the code that makes the above:
  
  <form name="form2" method="post" action="">
  <fieldset><legend>Personal Information</legend> 
  
  <p>name: 
  <input type="text" name="name">
  </p>
  <p>email: 
  <input type="text" name="email">
  </p>
  </fieldset>
  <fieldset><legend align="right">Comments</legend>
  <p>Please add your comments below:<br />
  <textarea name="comments" rows="10"></textarea>
  </p>
  </fieldset>
  </form>
Tab Order
  
  You can also set up a tab order for "tabbing" through forms with the: 
  
  tabindex="n"
  attribute. 
  
  ex. 
  -it can be added to anchor tags, <a href="page2.html" tabindex="3">About 
  Us</a> 
  -it can also be added to form elements:
  <form name="form1" method="post" action="">
  <input type="text" name="name" 
  tabindex="1" />
  <input type="password" name="funny" 
  tabindex="2" size="8" /> 
  </form>
ex.
code for the above:
  
  <form name="form1" method="post" action="">
  <p><a href="http://www.larabank.com" 
  tabindex="3">about Us</a><br>
  <br>
  name: 
  <input type="text" name="name" tabindex="1">
  </p>
  <p>password: 
  <input type="password" name="password" maxlength="8"
