Unwanted space in between menu items

Hi,
I have a peculiar problem here in my application. My application uses a menu that is using a css-javascript. the view of the menu in Mozilla is fine but there is an unwanted space at the top of the menu item in the menu/sub-menu which doesn't have child nodes. this problem is coming in both IE 6 & 7. how to fix this issue? appreciate your early help.

I have attached the css content below.

Thanks in advance.

regards,
Ravi.

at the last in your code you misspelled float as f\loat...
