You first need to setup the statistics that you want to record.
Do this in Setup > Statistic Setup
You can then add the individual stat types that you want to record when you enter the score for a match, we have some already created, but you can also create your own.
After you have added some stat types, you need to make sure that you have some players in the system.
You can create people and make them players in a team by going to:
People > List People > Player -- then press the 'Create New' button.
Fill in their name and which team you want to make them a player for.
After you have got all your players in the system you will be able to record these statistics when entering scores for matches by clicking on the button 'Enter Statistics' for a match in the result entry page.
