creating new columns with a for loop with column names and formula

FrequencyBison9

I am trying to create a split table from an existing table and add new columns into the split tables each with a formula based on the columns that were split. However the code creates the new columns but gives me "Formula evaluation errors"

 

dt2 = Current Data Table();

// Create the split data table
dt2 = dt << Split(
	Split By( :S ),
	Split(
				:Name( "Median(data)" )
			),
	Group( :L, :m, :C, :P, :z, :x ),
	Remaining Columns( Drop All ),
	Sort by Column Property
);
colname = {"B","C"};
colby = {"A","B"};

// Add new columns to the split data table
For( i = 1, i <= N Items( colname ), i++,
dt2 << New Column( colname[i]||"/"||colby[i],
	Numeric,
	"Continuous",
	Format( "Best", 12 ),
	Formula( column(colname[i]) / column(colby[i]) )
););

Try changing the Column() function to As Column() function
