Here is a simple example
names default to here(1);
dt =
// Open Data Table: Big Class.jmp
// → Data Table( "Big Class" )
Open( "$SAMPLE_DATA/Big Class.jmp" );
dtSumm = Data Table( "Big Class" ) << Summary(
Mean( :height ),
Freq( "None" ),
Weight( "None" ),
output table name( "Summary of Big Class" )
);
dtSumm << New column("Ratio", formula(:"Mean(height)"n/56))

If you are using the Tabulate Platform, you will need to generate the calculated value in the data table, and then display it in the Tabulate output

or create a virtual column in Tabulate and use it in the display

If this is not how you are creating your summary table, please provide a sample of what you are doing
