Why doesn't this work?

[jimmy joe jack]

-- FirstApp.lua
pmoveto(70,70)
plabel("My First App works!")
pevent()


I don't know how I could have messed this up. But I try to run it in plua and it's an error right at the pmoveto line. Also, I'm using source edit color-coded compiler, and it doesn't recognize any of the "p" commands. What gives?
