           src="http://captcha.swcp.com/ajax_captcha.js">

The CSS is to indent the CAPTCHA and draw a thin black line around it. This is completely optional.

  #imgCaptcha { margin: 0 30px; border: black solid 1px; }
  </style>

         <INPUT id="txtCaptcha" TYPE="text" name="verify" size=8
                 onKeyPress="onlyOnReturn(event, document.mfrwc)"; ><br>
  

A button to get a new CAPTCHA

This is in case the generated CAPTCHA isn't readable by the client, they can use this to get a different one. This is an optional button.

  <INPUT id="regCaptcha" type="button" value="Give me different text"
         NAME="regCaptcha" onclick="regenCaptcha(document.mfrwc)";>
  

Submit Replacement

This is required. Do not change the id or name of this button.

  <INPUT id="btnCaptcha" type="button" value="Send Comments"
         NAME="btnCaptcha" onclick="getParam(document.mfrwc)";>
  

Clear Form Button

This is also optional.

  <INPUT TYPE="reset" VALUE="Clear Form">
  

Status Area

This empty DIV is needed to display an error message when the user types in an incorrect CAPTCHA text.

  <DIV id="response"> &nbsp </DIV>
  

Note, the ids and the DIV are used by the Captcha scripts and must remain with the same names. The 'regCaptcha' button is for allowing the form user to regenerate a new text if they can't read the one that's presented.

Complete example with all necessary variables The values on the INPUT buttons can be changed to anything you'd like. The empty DIV named response is used to present an error message when the CAPTCHA is incorrectly typed and must be there.
