Extra comment field content not submitting

Hello everyone. I’m building a custom comment form and I have added a few extra fields. The problem I am having is that when submitted, the data in these fields doesn’t seem to appear when the comment is viewed on the admin dashboard. I’ve added the field names to my MySQL database, and the fields themselves appear in the edit comment page, just not the actual content.
If anyone could help me out I’d really appreciate it. Let me know what code you need and I’ll gladly post it.
