Hey @iracindy6490 !
Sorry to hear this has been your experience. I wonder if I might be able to help.
I’ve taken a read through your previous post looking for some help, and a quick look at your site.
From my understanding, you have a section underneath the header with the multistate box in it. I think you might have glanced over a step within the tutorial that explains that the multistate box needs to be moved and attached to the header so that it works across all pages. The header is a “global” part of the site, so attaching the multistate box to it ensures it’s present across all pages and the masterpage code (code that effects “global” elements) can work alongside it.
I’m linking the part of the video that explains this step and hopefully will help you out - How to Build Mega Menu using Multi State Box | Editor X - YouTube
Let me know how it goes, and good luck
