Promo code

Hi there,

I wonder if anyone can help me. I have a client that is running a competition & collecting consumers email address/phone etc.

What is needed though, is a field where the user enters a unique ‘promo code. Once this unique promo code gets entered and the submit button is pressed the form is sent, if the wrong code is entered the form is unable to be sent.

I have seen that Ninja Forms does an anti spam question/answer that will work for me, but is there another way of doing this through Ninja forms? As I don’t want it showing ‘Please answer the anti-spam question correctly’ if the field has the wrong code added in.

Thanks in advance.
