Declare globally and set from setup?

Hi.. I'm trying to set the value of a char array from inside setup but i'm facing errors..

Global declaration char website[] PROGMEM;

Inside loop: I have tried a lot of options and none of them worked.

void setup() { website = ""; }

Could anyone help me on this?

Thanks a lot.

Things declared in PROGRAM are in READ-ONLY memory and can therefore NOT be changed

const char website[] PROGMEM = "";

So that may be my problem....

Thank you guys!
