Seems like there's something wrong with your ZCMD. Anyways this code should work:

pawn Код:

COMMAND:request(playerid, params[])
{
    new fid;
    if(sscanf(params,"i ", fid))return SendClientMessage(playerid, 0xFF0000AA, "Usage: /request [orgid]");
    GetPlayerName(playerid, Name, sizeof(Name));
    if(IsInOrg[playerid] == 1) return SendClientMessage(playerid, red," You are already in a organisation!");
    if(IsRequesting[playerid] == 1) return SendClientMessage(playerid, red," You are already requesting to join an organisation!");
    switch(fid)
    {
        case 1:
        {
            format(String,MAX_PLAYERS,"* %s is requesting to join San Andreas Police Dept.",Name);
            SendClientMessageToAll(SAPD_COLOR,String);
            IsRequesting[playerid] = 1;
            request[playerid] = 1;
            return 1;
        }
        case 2:
        {
            format(String,MAX_PLAYERS,"* %s is requesting to join San Andreas Street Racers.",Name);
            SendClientMessageToAll(SASR_COLOR,String);
            IsRequesting[playerid] = 1;
            request[playerid] = 2;
            return 1;
        }
        case 3:
        {
            format(String,MAX_PLAYERS,"* %s is requesting to join Hitmen.",Name);
            SendClientMessageToAll(HITMAN_COLOR,String);
            IsRequesting[playerid] = 1;
            request[playerid] = 2; // I believe this should be 3?
            return 1;
        }
        case 4:
        {
            format(String,MAX_PLAYERS,"* %s is requesting to join The National Guard.",Name);
            SendClientMessageToAll(NG_COLOR,String);
            IsRequesting[playerid] = 1;
            request[playerid] = 2; // and this 4 maybe?
            return 1;
        }
    }
    return 1;
}

Even tho' there's a much more efficent way to do it.
This should also work if you rewrite some of your code:

pawn Код:

COMMAND:request(playerid, params[])
{
    new fid;
    if(sscanf(params,"i ", fid))return SendClientMessage(playerid, 0xFF0000AA, "Usage: /request [orgid]");
    GetPlayerName(playerid, Name, sizeof(Name));
    if(IsInOrg[playerid] == 1) return SendClientMessage(playerid, red," You are already in a organisation!");
    if(request[playerid] > 0) return SendClientMessage(playerid, red," You are already requesting to join an organisation!");
    if(fid < 1 || fid > 4) return SendClientMessage(playerid, red, " Invalid organisation id, must be between 1-4!");
    switch(fid)
    {
        case 1:
        {
            format(String,MAX_PLAYERS,"* %s is requesting to join San Andreas Police Dept.",Name);
            SendClientMessageToAll(SAPD_COLOR,String);
        }
        case 2:
        {
            format(String,MAX_PLAYERS,"* %s is requesting to join San Andreas Street Racers.",Name);
            SendClientMessageToAll(SASR_COLOR,String);
        }
        case 3:
        {
            format(String,MAX_PLAYERS,"* %s is requesting to join Hitmen.",Name);
            SendClientMessageToAll(HITMAN_COLOR,String);
        }
        case 4:
        {
            format(String,MAX_PLAYERS,"* %s is requesting to join The National Guard.",Name);
            SendClientMessageToAll(NG_COLOR,String);
        }
    }
    request[playerid] = fid;
    return 1;
}
