Being an IT professional, I (as a new user) have waded right into the deep end of the pool. A short time ago, I was able to contact support and actually open a real ticket. Got a great answer and my problem disappeared. Thanks, support.
The support person actually looked at my site and came back letting me know where the error was. But I can't get into the ticket system (just circular menus that go nowhere and don't help with my specific problem) so can't use that method again.
My problem is with dynamic pages. I duplicated the example on YouTube that even shows how to make he index. But it won't work for me. So, if anyone here would be willing to take a quick look at my site, I'd provide the login credentials, etc via PM, private Email or something similar. WIX appears to me to be one heluva tool, but I personally am having trouble getting my mind wrapped around it.
