For valid values for each option, see Using Data Form Scripts.
If a form requires more than 100 rows, you can use the Scripts tab to specify the additional rows. For information on the syntax to use, see Rn.
If a form requires more than 24 columns, you can use the Scripts tab to specify the additional columns. For information on the syntax to use, see Cn.
