I am having a problem adding a new link to a pulldown menu item written in javascript. When I add a new link, instead of appearing at the bottom underneath the previous 9 links, it jumps up to the top and "masks" the 1st link.

The page in question is here: JOANNE LEE - LOS ANGELES...NUTRIONAL CONSULTANT, PERSONAL TRAINER, FITNESS & CONDITIONING COACH

Under the "Store" menu item (the very far right of the menu), I am trying to add "DVD Seminars" link underneath "Fitness Equipment", but it is instead appearing at the top, covering up the link "Articles" (viewable in the code but not on the page).

Can someone please help?
Thank you!
