javascript - Meteor fetch on client undefined outside of helper -

i trying fetch entry in collection with:

client/views/home.js:

criticalcrewnumber = configvalues.find({   name: 'criticalcrewnumber' }).fetch()[0].value; 

but i'm getting error:

uncaught typeerror: cannot read property 'value' of undefined

if run code in browser console, desired value returned string.

i have tried various things, e.g. using findone; placing code elsewhere in app; using iron-router waiton subscription come, etc. every attempt far has failed end undefined.

here's how collection defined, published , subscribed to:

lib/config/admin_config.js:

configvalues = new mongo.collection("configvalues");  configvalues.attachschema(new simpleschema({   name: {     type: string,     label: "name",     max: 200   },   value: {     type: string,     label: "value",     max: 200   } })); 

both/collections/eventscollection.js:

if (meteor.isclient) {   meteor.subscribe('events');   meteor.subscribe('config'); }; 

server/lib/collections.js

``` meteor.publish('events', function () { return events.find(); });

meteor.publish('config', function () { return configvalues.find(); }); ```

does know what's going on? thanks.

consider using reactivevar (and meteor.subscribe callbacks):

criticalcrewnumber = new reactivevar();  meteor.subscribe('config', {     onready: function () {         var config = configvalues.findone({name: 'criticalcrewnumber'});         if (config) {             criticalcrewnumber.set(config.value);         } else {             console.error('no config value.');         }     },      onstop: function (error) {         if (error) {             console.error(error);         }     } });
