Urgent little programming work

When ever there is a category or section added to the url then the template formatting is lost. i.e the script to change the font and the images all links without any section or category work fine i had to disable my drop down menus because when used they create a category in the url and the formatting is lost. i.e. [login to view URL] works fine [login to view URL] will lose formating also pictures dont work. our Budget is only 25 $ . time limit is one day .
