if(strcmp(cmd, "/myskin", true) == 0)
{
    tmp = strtok(cmdtext, idx);
    if(!strlen(tmp))
    {
        SendClientMessage(playerid, red, "Usage: /myskin [skinid]");
        return 1;
    }
    new skin;
    skin = strval(tmp);
    format(string, sizeof(string), "You change your skin to this skin ID: %d", skin);
    SendClientMessage(playerid, COLOR_GREEN, string);
    SetPlayerSkin(playerid, skin);
    return 1;
}

This will work
