Code to show object doesn't show anything.

I was making some code for SteamVR when I ran into a roadblock, my code to show the square wouldn't show anything! Here's my code:

print(dir(vr))

Also as a debugging step put the square displaying code in Pink World, that didn't work. Also, does the object need to be a GL_TRIANGLE? Could that cause any problems? If so do you have example GL commands that I could try? Thanks! I'm trying the following instructions:
