// cant demote or promote cause I am not a leader, after I use /makeleader on myself. Gives me this :



and for the last part of it, my userfile looks like this:



P.S. - It doesn't save any of the data into this file, I was using this tutorial to create it:https://sampforum.blast.hk/showthread.php?tid=597639 But it doesn't save the data (with other users i have money on hand, and it still writes down '0' into the scriptfiles.)

I've made this cmd to check if I was assigned to id 1 faction, didn't work either..

CMD:cop(playerid, params[])
{
    if(PlayerInfo[playerid][Faction] == 1)
    {
        SendClientMessage(playerid, COLOR_RED, "YOU ARE A POPO");
		new Float:x, Float:y, Float:z;
		GetPlayerPos(playerid, x, y, z);
		SetPlayerPos(playerid, x, y, z+10);
	}
 	return SendClientMessage(playerid, COLOR_WHITE, "YOU ARE NO POPO");
}
