The stats do not show all the players in the game on the Stats page on the website but does show all the players stats if you go to the game page? Why?

That would mean you do not have the players in the Team Roster. Go to Teams in iScore, select your team, select Roster, and add any missing players there (be sure to select the players from the existing set of players, don't create a new player). Then do an Options -> Export after you have added the missing players and you will see cumulative stats for all your players.
