You have a block element (form) inside an li, this is "illegal." Try floating the form inside "navbar."
Also you might want ot resolve as many of these [validator.w3.org] as you can, particularly the ones relating to the table <tr> errors.
Aside, all of those tables can be eliminated, but this veers O.T.
