I’ve tried so many times and still can’t get this to work. For my attempts to get it to work prior to writing you, I did have a username field assigned. It was the text field labeled name. I’ve tried many more times since your response and still no luck. I watched the video but it’s nothing new to me. I was doing everything as shown in the video. I’ve mapped the fields, to the best of my knowledge, correctly. No extra spaces. Just added the WP field number. I even tried assigning the email field as the username. The only way I’m able to get it to actually create a subscriber is by adding plain text such as “hello” as the field instead of {9:form_field:1} .
