Variables problem

Code:

local a = {}

a[1] = 1

a[2] = 2

Goal:

Code:

a[1] = 2

a[2] = 1

I want those two to switch their values, but it seems like I always end up with references and both having the same value.
What is the correct way to do it?

Thanks

Code:

local tempVar = a[1];

a[1] = a[2];

a[2] = tempVar;

As far as I'm aware there's no command in Lua to say "switch the contents of these two variables", so you have to use a temporary holding variable to do it.

Are you trying to do a sort, or just to swap the values?

What I'm trying to do is swapping two statusbars, but I seem to fail.

Code:

a[1], a[2] = a[2], a[1]

will work fine, no need for a temporary variable.
