You suddenly open a bracket and then you use else statement without an if before. I'm not aware of what your command is supposed to do so either:

pawn Код:

dcmd_bot(playerid,params[])
{
    #pragma unused params
    if(pInfo[playerid][Adminlevel] < 1) return SendClientMessage(playerid, COLOR_RED, ""ERROR_MESSAGE"");
    if (/* SOME EXPRESSION */)
    {
        SetPlayerAttachedObject( playerid, 0, 19078, 1, 0.337255, -0.102219, -0.170282, 0.000000, 0.000000, 0.000000, 1.000000, 1.000000, 1.000000 );
    }
    else
    {
        RemovePlayerAttachedObject(playerid, 1907;
    }
    return 1;
}

or

pawn Код:

dcmd_bot(playerid,params[])
{
    #pragma unused params
    if(pInfo[playerid][Adminlevel] < 1) return SendClientMessage(playerid, COLOR_RED, ""ERROR_MESSAGE"");
    SetPlayerAttachedObject( playerid, 0, 19078, 1, 0.337255, -0.102219, -0.170282, 0.000000, 0.000000, 0.000000, 1.000000, 1.000000, 1.000000 );
    RemovePlayerAttachedObject(playerid, 1907;
    return 1;
}

That depends on you.
