page format

Hello

Maybe an easy fix but I’m dumb. I’m not a code guy. My layout is classic on wjtassociates.com. In the Left Hand column I have a link(seminars) – it goes directly to a book store. I want to either delete it or change it to link to a page of text. If I delete it, I need to put a new link to replace it.

Can anybody point me to a step by step arrangement to fix it?

thanks
