p is set at the top of the code on line 8 using peripheral.wrap. The wiki says:

Returns a table of functions, allowing you to call peripheral methods as if they were normal Lua functions. If no peripheral is connected, returns nil.

Check to make sure you have the peripheral connected on the given side (It is set to "right").
