Setting up Jog Buttons

Hi,
I am setting up jog buttons similar to the example here: www.linuxcnc.org/docs/2.4/html/hal_pyvcp_examples.htm

when I launch EMC I get the following error:
Pin 'halui.jog.0.minus' does not exist

My custom_postgui.hal file looks like:
# connect the X pyVCP buttons
net my-jogxminus halui.jog.0.minus <= pyvcp.x-minus
net my-jogxplus halui.jog.0.plus <= pyvcp.x-plus

# connect the Y pyVCP buttons
net my-jogyminus halui.jog.1.minus <= pyvcp.y-minus
net my-jogyplus halui.jog.1.plus <= pyvcp.y-plus

# connect the Z pyVCP buttons
net my-jogzminus halui.jog.2.minus <= pyvcp.z-minus
net my-jogzplus halui.jog.2.plus <= pyvcp.z-plus

# connect the pyVCP jog speed slider
net my-jogspeed halui.jog-speed <= pyvcp.jog-speed-f

IF I comment out the lines above I am able to load EMC and see the panel with the buttons, of course they dont work when commented out but the program runs.

Can someone point me in the right direction?

That was it....you are da man!
Sorry for my Newbieness!
