formulas not working

[#1]

I am using Windows and JMP 18

Im Having some problems with version 18

My most recent one is that calculation of formulas does not work.  So for example

I have two columns X and Y - both continuous numeric variables  If  make a variable  Z (also numeric continuous) and use a formula in it: X * Y

I get nothing  (just dots)

any ideas??

[#2]

just use the formula

:X * :Y

or if "It" is the reference to the data table you could specify

It = current data table();
It:X * It:Y

The JMP Log might have an error statement

the easiest way to generate a new column: new formula column right click menu:

and then you can go to the Log and check the code ...
