How to store data from serial to PROGMEM?

Ok so I was at work and didnt have access to y arduino at the time..

And nope it didnt work.

The arduino IDE showed this error:

sketch_may12a:22: error: 'inData2' was not declared in this scope

So I guess I'm not understanding how this code works.

I thought that this section of code:

struct config_t
{
    char inData2[12]; // Allocate some space for the string
} configuration;

Replaced me having to set up:

    char inData2[12]; // Allocate some space for the string

Prior to my running code.

Does anybody know of the glaring mistake im making?
