I have changed the button set on my site www.dvdtitan.co.uk to the blue bold buttons which i downloaded.

All buttons have changed to the new set apart from the search button in the search sidebox that came installed with my zen cart when i bought it.

Can anyone tell me how i change this button to fit in with the rest of the button set i have succesfully installed. It's been drivng me crazy trying to find the right button to change.

Thanks in advance.
