troubleshooting Question
How to resolve the CAPTCHA script inside my ASP form?
asked on
Dear EE Experts,
Please see the attached codes that we have, kindly check & advise why does the CAPTCHA script isn't working, what I mean is if a user type it wrong, it will still send the form, it's not checking the spelling...
