Applying Constraints
Now that you have data grids, you need to add some constraints to them. Because data grids aren't database objects,
you must use the websheet interface to apply constraints.
In the Players data grid, you need to ensure that all the fields contain data and that the default for the Goals
column is 0. To apply these constraints, follow these steps:
1.
Click the
Data Grid
tab.
2.
Click
Players
in the drop-down menu.
3.
Click the
Manage
button, and select
