- Subject: When to clean the stack?

I have a script for which I want a return value.
Usually something like this:
scriptstring = "strength = 10 agility = 10 calculated_attribute =
strength + agility"
(of course, this is a nonsense script, but you see what I mean).
How do I get the "calculated_attribute" back out of LUA?
I assume I would use lua_getglobal() -- how do you use this function?
I was thinking it would be something like this (in pseudocode):
if (lua_isnumber(L,???) // what to put here?
attribute = lua_tonumber(L,???);
// should I clean the stack here? or does lua_tonumber do it?
attribute = 0;
Is there a better way?
Thanks for any input.
