One of the items in my dropdown list is "Other". When the user clicks on it I want to open a new text box where user can enter the values. How do I do this?

You have to use divs to hide and show a form element. Pay attention to Netscape HTML coding here. Below is a simple form element showing and hiding example

Below is a list of items you have to be careful about

Form element to be hidden, must be in another form (For Netscape).

This form must be in a div.

Remember that forms can not be nested.

copy and paste the code and try it.

<html> 
<head> 
    <title>FORM</title> 
<SCRIPT LANGUAGE="JavaScript" TYPE="text/javascript"> 
<!-- 
function showHideSelection() 
  { 
   if (document.form1.gor.checked) 
    { 
     if (navigator.appName=="Netscape") 
      document.layers['formdiv'].visibility = "show"; 
     else 
      document.all['formdiv'].style.visibility = "visible"; 
    } 
   else 
    { 
     if (navigator.appName=="Netscape") 
      document.layers['formdiv'].visibility = "hide"; 
     else 
      document.all['formdiv'].style.visibility = "hidden"; 
    } 
  } 
//--> 
</SCRIPT> 
</head> 

<body> 

<form name="form1"> 
    <input type="checkbox" name="gor" onclick="showHideSelection();"> Show options
 
</form> 

<div id="formdiv" style="position:relative; visibility:hidden;"> 
<form name="form2"> 
<select name="secme">
