captcha not verifying entry

I can't get the web wiz captcha to verify the entry.

This is my form handler.

<!-- Include file for CAPTCHA form processing -->            
<!-- #include file="CAPTCHA/CAPTCHA_process_form.asp" -->

If blnCAPTCHAcodeCorrect = True Then
            Response.Write(" CAPTCHA code is correct")
Elseif  blnCAPTCHAcodeCorrect = False Then
            Response.Write(" CAPTCHA code is NOT correct")
            Response.Write("<a href=""javascript:history.back(1)"">Click here to amend</a>")
