OK. I moved the layout code, and now I'm down to 16 errors. I can't really tell why some of them are errors, and I can't tell if the ones listed are causing any of the problems.
But it seems that sometimes, and not just when clicking on the back button, but when just clicking on the "add listings" link, sometimes the table shifts to the left, and sometimes it's centered (where it should be).
What's also really weird is that the code for this "add listings" page and the "search listings" page (below) are the same except for the items in the table. But for some reason, the "search listings" page doesn't do that weird shift thing that the "add listings" page does.
Search Listings
Any thoughts???
