Question Count Items in trade offer

[TextDynasty]

Hi.

I want to know how to count items in trade offer to make trade offer more useful

i've tried this code but it didn't seems working

 

var item_from_me =

{

    "appid": 440,

    "contextid": 2,

    "amount": 1,

"assetid": "5148534535",

    "item.name": "Refined Metal"

}

 

var item_from_them =

{

    "appid": 440,

    "contextid": 2,

    "amount": 1,

"assetid": "5158673853",

    "item.name": "Mann Co. Supply Crate Key"

}

offers.on('newOffer', function (offer) {

    if (offer > 0) {

    offers.getOffers({

      get_received_offers: 1,

      active_only: 1,

      time_historical_cutoff: Math.round(Date.now() / 1000)

    }, function(error, body) {

      if(body.response.trade_offers_received) {

        body.response.trade_offers_received.forEach(function(offer) {

          if (offer.trade_offer_state == 2) {

            console.log(offer);

            console.log('Recieved trade offer: ' + offer.tradeofferid);

            if (offer.items_to_give === item_from_me * 22 && offer.items_to_recieve === item_from_them) {

              offers.acceptOffer({tradeOfferId: offer.tradeofferid});

              console.log("Offer accepted");

              if (offer.steamid_other !== admin) {

                steam.sendMessage(admin, offer.steamid_other + " just donated!");

              }

            } else {

              offers.declineOffer({tradeOfferId: offer.tradeofferid});

              console.log("Offer declined");

            }

          }

        });

      }

    });

  }

sorry my bad. 

offers.on('newOffer', function (offer) {
manager.on("newOffer", function(offer) {
	var onlyKeys = (offer.itemsToReceive.every(function(item) {
		return item.name == "Mann Co. Supply Crate Key";
	}));
	var onlyRef = (offer.itemsToGive.every(function(item) {
		return item.name == "Refined Metal";
	}));
	if (onlyKeys, onlyRef) {
		keyAmount = offer.itemsToReceive.length
		refAmount = offer.itemsToGive.length
		console.log("Received trade offer containing " + keyAmount + " keys, accepting");
		if (keyAmount == refAmount * 21)
		offer.accept(function(err) {
			if (err) console.log(err);
		});
	} else {
		console.log("Trade offer contains non key items. Declining");
		offer.decline(function(err) {
			if (err) console.log(err);
		});
	}
})
}); 

i tried something like this but it doesn't accept my offer. any ideas?
