Undefined index in form with checkbox

I had a form working with a couple of checkboxes using the mail()
function that takes the user to a simple "thanks for your input" page
using the header() function at the end. But, instead of this, I wanted
to be able to print the results of their input. So, after the mail()
part, I had replaced the header() part with print() but am getting this
error now for the box that was not checked.

Notice: Undefined index: bw in C:\wwwroot\test.php

Here is what I had working before I changed the header() to print():

$color = $_REQUEST['color'] ;
if($color == "on"){echo" CHECKED";}
$bw = $_REQUEST['bw'] ;
if($bw == "on"){echo" CHECKED";}




I'm a little new to PHP.

I fixed this by turning error_reporting in the php.ini file to Off.

That is NOT a fix! Turn error_reporting on again and use
http://www.php.net/isset to see if the key exists.

Example:
if (isset($_REQUEST['bw']) && $_REQUEST['bw'] == "on"){echo" CHECKED";}
