"For Each Row()" is not a valid message to be passed to a data table, therefore,

dt << For Each Row(

just returns

Scriptable[]

The script works fine if you remove

dt <<

Names Default To Here( 1 );
dt = Data Table( "DATA" );

For Each Row(
	If( Contains( :Param, "P1 %" ),
		:Param = ":MAIN_PARAMETER"
	);
);
