ReferenceError: offer is not defined

[jafix]

Hi, i currently have a really short script for trading but it keeps on giving me that error.

My current script:

manager.on('newOffer', function (steamID, respond) {
    console.log('New offer from' + offer.partner.getSteam3RenderedID);

    if (offer.partner.getSteamID64() === 76561198259000054 || offer.itemsToGive.length === 0) {
		offer.accept();
	}
});

And on the start:

var TradeOfferManager  = require('steam-tradeoffer-manager');
var manager            = new TradeOfferManager({
    steam: client,
    community: community,
    language: 'en'
});

Switch steamID, respond for offer
