Suggest you look at your code and make some corrections. You do not have a doctype. From some of your tags I think you want html5 so I added that and everything goes to hell.
Maybe because you have inline tags that should be css.
You have two <body> tags both have depreciated attributes or unknown attributes.
The biggest thing you can do for yourself is to start using div's to position html elements and not tables. Even when tables were the only way to do things putting tables inside of a table slowed loading time and was never recommended.
Lastly you do not have a combobox drop down list in your code.
