Can't measure current in subcircuit

I pasted a subcircuit definition into the schematic editor.
The subcircuit works as expected.
I can’t view the current in the waveform viewer by clicking on the subcircuit that was pasted.
BTW, I used the standard box that QSPICE provides for the circuit, which I re-sized.

In the “Compose Expression to Plot” dialog, available via Ctrl-A in the waveform viewer, press the “Asterisk Matched Hierarchy Separatior” radio button.

Thanks for the guidance.
