first down?

At a high school game, the opponent was trailing and on their 4th down, with less than three minutes left in the game. They went for the down as opposed to punting. The officials had the chain gang come out, and the official appeared to rock the ball forward. The ball was still a good 6 inches inside the marker, however it was ruled a first down, changing the outcome of the game. Many of us have this on tape and were quite upset.

Did we miss something? We heard that our team's last game will have these same officals and we are not looking forward to that. However, if there is something that we don't know, we will accept this call.
