newbie help with captcha element
I have tried adding WA captcha to a form and get to the point where I need to set up the vailidation, following the steps on the tutorial I get to where I select server variable by clicking the lightning icon and I see session, captcha_security_code_1 and underneath the forms but I do not see the Server Variables entry as shown in the tutorial. I have just set up a local testing server using xampp specifically to use this facility but although I believe I have set it up correctly I am getting the above issue.
It is almost as though there is a step missing in the tutorial, how do I get the "Server Variables" element to appear in the panel.
Any help with this is appreciated.
Thanks in advance
