Hi!
I have this code:
Code:

file = io.open("highscore.txt","r")
record_score = file:read()
file:close()

But, when I try to print record_score string with
Code:

screen:print(0,0,""..record_score,color)

LuaPlayer return an error, "record_score is a nil value"
Whi?

See the file io tutorial here: http://www.evilmana.com/tutorials/lua_tutorial_09.php

It looks like maybe the open() function failed, thus the read() failed also.

Error check that they return successfully.

Also, to read a number you need to pass *n to the read() call.
