or you could just use format:
try this

pawn Код:

if(dialogid == DPORIJEKLO){
        if(!response) return KickWithMessage(playerid, RED, "Morate izabrati drzavu iz koje dolazite kako biste se registrovali(Kickovani ste!)");
        if(response){
            if(listitem == 0){
                format(pInfo[playerid][pPorijeklo], 128, "Hrvatska");;
                PlayerTextDrawSetString(playerid, registracija[11][playerid], "Hrvatska");
            }
        }
    }

----------------------------

Edit: I think you can simply do that:

pawn Код:

pInfo[playerid][pPorijeklo] = "Hrvatska"; //= add "" to Hrvatska

I believe that format is the best solution (first suggestion)
