"Object not found!" error on a new page manually added, only the first time clicked

Hi guys, I need some help here. If you go to my website home page and look at the right column, under "important links", there are some links made by easypage, directing to new pages created manually. The problem is that every first time I click the " trade-in program" link after I cleared cache, temporary internet files, etc, gives me an "Object not found" error. But the second time click will be fine.

It looks like that the first time I click on it, the URL directed to is "http://bridgecampus.com/catalog/tradein.html&zenid=51b62a7bd238e15****c818cad4d01" with "zenid" in it, while any further clicks don't have it there. That might be the problem?

That trade-in program page is added by the method explained here.

Anyone can tell me how to resolve that? Thanks so much!

Robin
