I'm new to scripting. I was making /pm cmd. this is the code:-

PHP код:

public OnPlayerCommandText(playerid, cmdtext[])
{
 if (strcmp("/pm", cmdtext, true, 10) == 0)
    {
    new str[128],id,pname[MAX_PLAYER_NAME];
    if(sscanf(params, "us", id, params)) SendClientMessage(playerid, 0xFF0000FF, "Usage: /pm <id> <message>");
    else if(id == INVALID_PLAYER_ID) SendClientMessage(playerid, 0xFF0000FF, "ERROR: Player not connected");
    if(playerid == id) SendClientMessage(playerid, 0xFF0000FF, "ERROR: You cannot pm yourself!");
    else
    {
        GetPlayerName(id, pname, sizeof(pname));
        format(str, sizeof(str), "PM To %s(ID %d): %s", pname, id, params);
        SendClientMessage(playerid, 0xFF0000FF, str);
        GetPlayerName(playerid, pname, sizeof(pname));
        format(str, sizeof(str), "PM From %s(ID %d): %s", pname, playerid, params);
        SendClientMessage(id, 0xFF0000FF, str);
    }
    return 1;
}
    return 0;
} 


These are the errors I'm getting:-

PHP код:
