RPints uses board numbers (from the python):
GPIO.setmode(GPIO.BOARD) # Broadcom pin-numbering scheme
so you should use pins 18 and 22 for the 2 you are testing and verify the other 2 are valid also (even if not hooked up)
If you look under the advanced hardware menu, there is a hardware IO display admins screen that should show you what pins you are using and what for, though im not sure if you configure for invalid pins (e.g. ground) if it will still show the hardward you configured for it. But you can see the layout RPints is using.
ok when I use 18 and 22 it tries to take a measurement from the load cell but measures 0 everytime and then errors out.
When I look at the hardware IO I have "response" on 18 which is my Data line from the hx711 and I have "Command" wired to 22 which is my CLK for hx711
