Analysing module in testbench using questa

Hello,

I've written a basic program to try and get the testbench program on questa to work - I've been using $monitor and $display all semester. I can't seem to get it to show anything. I'd like to see all the variables in each module, regardless of whether they're in the top module or not an input or output.

I understand how to put a testbench into the program using settings.

Specifically, I'd like to see the values of y and z. What am I doing wrong?
