I'm testing CAPTCHA before buying the license. I entered the code as instructed to the form & processor page.

The only difference I see is on my processor form but I'm not sure if this has any impact:

<%@ Language="VBScript"%>



<%
'If CAPTCHA is entered correctly run the following code
If blnCAPTCHAcodeCorrect = True Then

'Place code here that is to run if CAPTCHA is entered correctly
Response.Write("CAPTCHA code is correct")

'If CAPTCHA is NOT entered correctly run the following code
ElseIf blnCAPTCHAcodeCorrect = False Then

'Place code here that is to run if CAPTCHA is NOT entered correctly
Response.Write("CAPTCHA code is NOT correct")
End If
%>

Each time, the processor page tells me that the code was not entered properly even though I've entered the correct one. What am I doing wrong here?

I didn't tell it to redirect yet because I want to make sure it's working first. I can't figure out why it keeps stating that the code wasn't entered correctly when I did enter it several times. The example files run fine.

Make sure that session variables are working correctly on your site.

Sorry - sort of new to this. Where would I check this?

Probably the simplest way is to place at the top just before the CAPTCHA_process include the following:-

<% = Session("strSecurityCode") %>

This will display if there is anything in the session variable which is passed across from the previous page displaying the CAPTCHA code.

I have this exact problem too. Keeps stating the captcha code was entered wrongly. I followed the advise above and I can see that a different code is being passed through (I guess it is rembering an old code). I don't know anything about session variables. How do I solve this?

Sounds like you could be using load balanced web servers or multi worker process for the website. Some things that can stop ASP Sessions from working are:-

Fault on the server or dodgy site coursing the application pool to recycle
Load Balanced web servers
Multiple worker processes in the application pool
Application pool recycling to often due to incorrect settings
ASP application on the website uses 'Session.Abandon'
