Accessing the probe, from a panel ( SOLVED )

I can't believe I'm having so much trouble with this. Clearly it should work, since I see lots of other folks doing it with ease. An example is this post/thread from AskJerry: forum.linuxcnc.org/22-pyvcp/28572-monste...achine?start=0#53197

I have a working panel, which gives me status on the jog parameters from my USB gamepad. It works great

All I want to do is add an LED to the panel, which reflects the state of the probe input.

The probe works correctly, and if I open "HAL Configuration" in Axis and do a watch on "motion.probe-input", it turns on and off as it should. It also tells me that signal "probe-in" connects "motion.probe-input" and "parport.0.pin-13-in", as I expected.

But if I addto my custompanel.hal, as I've seen others do, I get:
What am I, or might I be, missing? I've searched the pyvcb source file, example files, documentation files, for any references to the probe and pyvcb, and have come up empty.

I'm running 2.7.14. Is that way too old?

Argh!!! I was about to say "yes", but I had some leftover testing code in the xml file, so it wasn't spelled right. I suspect I've had either typos, or other errors, in either the hal file or the xml file, all afternoon. Thank you. Once I get them in sync, it works fine. Sheesh.

Solved. Thanks.
