If you are on, say, the Profile page, then you would set this variable to 0 - because this is the 'Profile' button number.
It should remain red to indicate that the user is on the Profile page. Eg: var ButtonNoNotToSwap=0; var ActiveImage="ProfileA.gif"

If you are on a page where all buttons should have a hover effect then define (but not initialise) the variable.
Eg: var ButtonNoNotToSwap; var ActiveImage="";
