I just switched booking services, now the custom fields I added to my theme do not show at checkout. They still display on the product page and customers can fill them out, but it does not save when they checkout. How can I fix this?

Theme: Artisan

Disregard this question, I’m getting ready to change to a new theme. My current one isn’t even 2.0 compatible and I’m realizing how much better that update is.
