I had to give up all earlier versions to install JMP12 so can't test this directly but suspecting syntax like this fails in earlier versions?
summarize(dt,var=by(columnname));
Yes, that's new in JMP 12.
Here's what you get in JMP 11.
dt=open("$SAMPLE_DATA\Big Class.jmp");columnname=column("Age");summarize(dt,var=by(columnname));/*:Must be Assign Operator in access or evaluation of 'dt' , dt/*###*/In the following script, error marked by /*###*/dt = Open( "$SAMPLE_DATA\Big Class.jmp" );columnname = Column( "Age" );Summarize( dt/*###*/, var = by( columnname ) );

Thanks! Discovering it the hard way by accidentally using that in a script to be run by folks who haven't updated to JMP12 but it's a good feature.
