You forgot "Graffiti" before [playerid].

pawn Код:

strcat((Graffiti[playerid][active_character[playerid]][asicerik][0] = '\0', Graffiti[playerid][active_character[playerid]][asicerik]), inputtext, 128);

A way easier would be to use macro for it:

pawn Код:

#define strcpy(%0,%1,%2) strcat((%0[0] = '\0', %0), %1, %2)

and the usage:

pawn Код:

strcpy(Graffiti[playerid][active_character[playerid]][asicerik], inputtext, 128);

Note that the array should be declared:

pawn Код:

new Graffiti[MAX_PLAYERS][MAX_GRAFFITI][grafInfo];

since you have one more index (playerid).
