CAPTCHA Code Still Not Working - Web Wiz Support and Community Forums

Sorry about the lag, I'm over here in the colonies, so I just woke up...

As requested, instructions/code for a single-page e-mail form using WWG CATPCHA. I'm assuming that you have everything installed where it needs to be.

Step 1: Remove the line  from the CAPTCHA_form_inc.asp file

Step 2: Construct your mail form page as follows (comments are in blue):

<%@LANGUAGE="VBSCRIPT" CODEPAGE="1252"%> 



<body>


<%
If Len(Request.Form("sender")) > 0 then

'checks to see if there's any information in the sender field of the form; this serves as both rudimentary prevention of blank forms and as a yes/no check on whether a form has been submitted; you'll see why that second part is important in a minute

    If blnCAPTCHAcodeCorrect = True Then 'If they get the code right
    'send the message
        'CDONTS code snipped
        Response.write("<h3><i><font color='ffffff'>Your message has been sent to LowGenius Web Design. We will be in contact with you as soon as possible. Thank you!</font></h3></i>")
    ElseIf blnCAPTCHAcodeCorrect = False Then ' if they get the code wrong, tell them so
        Response.Write ("<h3><i><font color='ffffff'>You have entered an incorrect code for the CAPTCHA humanity test. This code help reduce abuse of our contact form by automated systems. Please use the 'Back' button on your browser to try again.</font></h3></i>")
    End If    'note that this ends the NESTED If; we're still inside another If...Then...Else loop
Else 'If there is no information in the Sender field, assume that the form has not been populated, and display the form
%>




<% End IF ' and now we break out of the larger if-then-else statement %>


The idea here is this: If you load the variables from the setup include at the top of the page, then they're active regardless of whether a form has been submitted or not. If a form has NOT been submitted, then those variables just remain empty but have been declared so you don't run into problems when the captcha include file tries to define them. If a form HAS been submitted, then the variables are declared and then populated with your processing code. It's probably not great practice to have declared variables laying around undefined; if you're a real stickler for detail you can set them to 'nothing' in a code block after the end of your form but BEFORE your final End If; otherwise you'll clear them when the form is submitted and you will end up constantly 'failing' the captcha test.

Please feel free to yank (no pun intended) my chain if you need more clarification; brevity is not my strong suit.
