Can someone tell me what the difference is between;
uploadproduct.tmpl
uploadproduct1.tmpl
uploadproduct2.tmpl
uploadproduct3.tmpl
They essentially look the same to me, is there a difference in these, and if so what is it? Are they're any docs or instructions to what these are?
I am trying to figure out how to remove the no expiration time length and want to make sure I am doing it in the right place(s), or if there is a better way or place to accomplish this task that would be great too

Thanks
joey
