I have created a custom form using the API so that the form will match the site and only display fields I want the user to fill out. However currently I have it where the Interest List shows up to the right and lets the user choose which List to join.
How to I alter the code to force them to join the one list I want them to join and not show that sidebar. I have three lists in total but 2 of those are for testing purposes. I don't want to give the user a choice in which list they want to join. They just fill out thier name and email and birthday and click submit. Thanks.
