Landing page. Form. Spam Proection. "Invalidhoneypotvalue".

I have the "Form Spam Protection" enabled on my form and have selected the "Custom honeypot field name" option. It defaults to the value of "customHoneypot". I do not have an actual hidden honeypot field on my form. I have this form on an Eloqua Landing page and do a test submission. The submissions go to the Form Spam data with the Block reason last as "Invalidhoneypotvalue". What am I missing? What else do I need to do to get this to work?
