Oscommerce

[j&p04]

Hi, having read and watched the tutorials to change the index page in oscommerce, I am no further on from when I started. In the first instance, the screen shot they show in the tutorial is totally different to the one that comes up in oscommerce file manager, nonetheless I still tried to do as said, having one computer to work on and another to watch the tutorial step by step. I downloaded the index.php and edited it in another file, as was told to, saved it, then uploaded it into the public_html but it just put it in the list along with the original index.php. How do I overwrite the original.

I really feel stupid because I have seen lots of sites using oscommerce with their own logos, banners, colours etc, but cant seem to do it myself!!!!!

Please help.
